I. Introduction
Scientists have long been interested in the properties of solids, liquids, molecules, and other forms of condensed matter. Not only do the ordinary material substances that surround us—and the exotic ones that can be created only in controlled laboratory conditions—exhibit fascinating properties that pique our curiosity and invite explanation, but those properties often prove useful for accomplishing practical ends. However, despite the long tradition of scientific investigations into matter’s properties, condensed matter physics is of recent vintage as a distinct field of physics. Its emergence as a field required the advent of quantum mechanics, which provided the theoretical grounding a mathematical language that could explain those properties that we have found both fascinating and useful for so long. This Resource Letter focuses on describing the historical resources that collectively tell the story of the application of quantum physics to condensed matter, the experimental techniques that made it possible, the technological outcomes of such research, and how these threads combined to form the field of condensed matter physics.

The history of condensed matter physics is a relative newcomer to the history of science. Navigating that history requires careful attention to terminology. Searching for “history of condensed matter physics” in search engines or databases is unlikely to yield many results, but this should not be mistaken for a lack of material on the subject. The name “condensed matter physics” did not become standard until the 1970s, when it began to take the place “solid state physics,” itself little-used before the 1940s, among some segments of the physics community. Whereas physicists are likely to regard the term “solid state physics” as outmoded, or to think of it as referring only to the subfield of condensed matter physics dedicated to solids with regular crystal lattices, historians who study times when “solid state physics” was more widely used to identify what we would now call condensed matter physics prefer to remain true to the eras they study and use older phrase. Furthermore, neither term was used as a name for a scientific field before World War II, when the research programs that would eventually compose it fell within acoustics, optics, mechanics, thermodynamics, metallurgy, quantum physics, quantum chemistry, high pressure physics, low temperature physics, x-ray crystallography, and other specialties.

The challenges of terminology are compounded by the fact that condensed matter physics is a broad and diverse field. In addition to research on regular solids and the behavior of fluids, it encompasses work on liquid crystals and quasicrystals, colloids and gels, glasses and ceramics, granular and soft matter, polymers and other complex molecules, and other subjects. Research we would today classify as condensed matter physics might at one point have been—and in some contexts might still be—identified by terms such as solid state physics, many body physics, low temperature physics, statistical physics, physics of complex systems, semiconductor physics, materials science or materials physics, nanophysics, mesoscopic physics, chemical physics, quantum chemistry, solid state chemistry, or others. Here, I focus most sharply on those fields that were considered element of the core of solid state and condensed matter physics in their own times. Many of these research traditions have roots reaching into the very early twentieth century, or even the nineteenth. To avoid venturing too far afield, I limit discussions of the early theoretical and experimental headwaters of research programs that eventually found themselves included within condensed matter physics, except where such origins are particularly notable.

The historical literature addressing condensed matter physics has only begun to scratch the surface of all the topics, research programs, disciplinary classifications, national contexts, and institutional settings it includes. For the purposes of this Resource Letter, I have, from necessity, emphasized certain elements of this complex amalgam over others, focusing mostly on those areas that have received the greatest attention from professional historians. What follows therefore reflects biases inherent in the literature by beginning from the early days of solid state physics and following forward those research programs that defined it in its early stages and which continued to dominate when “condensed matter physics” became a preferred disciplinary classification in the 1970s and 1980s. It also reflects a bias toward the American context, which is the most thoroughly explored by English-language works. Although these elements of the history of condensed matter physics are the most thoroughly explored at the present moment, they should not be mistaken for whole story, or even for its better part, and where applicable I have sought to direct readers to resources that can fill out the stories I cover in only a cursory manner here.

The direct relevance of much of condensed matter physics to technological applications adds another wrinkle to its history. Condensed matter physics grew alongside multi-disciplinary technical enterprise such as materials science and nanotechnology for much of the second half of the twentieth century, and these technologically oriented fields frequently included solid state and condensed matter physicists as critical collaborators. As a result, the history of technology literature is often relevant for understanding the development of condensed matter physics. A comprehensive perspective on the history of condensed matter physics therefore requires considering how our scientific understanding of complex material systems grew alongside questions of how the physics community organized to pursue that research, how and why societies supported it, and how it connected with industrial development.

This Resource Letter offers a guide to each of these dimensions of the history of condensed matter physics. It presents some general resources, followed by targeted sets of references that describe: the conceptual development of the field; its institutional and community structure; its social, cultural, and political history; and the longstanding connection between condensed matter physics and technology. Finally, it concludes with some reflections on future directions for research in the field.

N.B.: Many of the sources listed below are relevant to multiple categories. To decide where to place sources that address multiple themes, I have considered how well they complement the other sources in the category.

III. Conceptual Development of Research Programs
Condensed matter physics is a broad, diverse field, and the range of topics it contains makes telling its history challenging. Historians often meet this challenge by focusing their attention on the progress of a particular theory, experimental technique, or research program. Many such studies focus on the era between the advent of quantum mechanics in the 1920s and the Bardeen-Cooper-Schrieffer theory of superconductivity in the late 1950s, making the conceptual history of condensed matter physics during this era the best studied of its many historical dimensions. The list below presents studies of this variety in rough chronological order, beginning with early twentieth century applications of quantum physics to condensed matter.

The early twentieth century was a time of considerable interest in the physics of condensed matter as a testing ground for the new quantum physics. The theory’s successes and failures in the realm of molecules and solids describing phenomena such as bonding, conductivity, and magnetic susceptibility helped pave the way from the old quantum theory to the new quantum mechanics, which was elaborated throughout the 1930s by incorporating concepts from the condensed matter domain, such as tunneling, resonance, and exchange.

In the 1940s and 1950s, the established tradition in the quantum theory complex matter was bundled with a diverse set of other research programs to create a new field, solid state physics. It was a wildly diverse synthesis of research programs, and a few of these quickly gained prominence, often on the strength of their industrial relevance. The invention of the transistor at Bell Laboratories in 1947 made semiconductor research one of the liveliest areas of physics. A strong community came together around nuclear magnetic resonance, which grew from World War II radar research. The long-awaited theoretical description of superconductivity, which both reinforced the intellectual challenges posed by the physics of complex matter and promised a raft of new applications, made low-temperature work central to solid state physics in the late 1950s.

Later in the twentieth century, segments of the solid state physics community became frustrated with fact that funding for solid state research was often tied to technological development, and aimed to reinforce the intellectual value and viability of their research. These efforts led to a resurgence of interest in fundamental questions that appear in the condensed matter domain. This involved an intellectual disagreement between condensed matter physicists and high energy physicists over the importance of reductionist thinking for physics, which shaped the conceptual development of both fields.

IV. Institutional Evolution and Community Structure
The research programs that made up solid state and condensed matter physics were thoroughly international throughout the twentieth century, but the first institutions dedicated to the field appeared in the United States after World War II, at which point the community of researchers interested in the physics of condensed matter had become large enough to establish its own institutions and worry about its community structure. The Division of Condensed Matter Physics of the American Physical Society (APS) was founded in 1947, largely on the back of the efforts of the General Electric research physicist Roman Smoluchowski. It was originally proposed as a division for metals physics, and was envisioned as a way to give industrial researchers—a growing constituency in the APS—a home within the society and a greater say over its organization and polices. The division was called the “Division of Solid State Physics” up until it adopted its current name in 1978. Historical examinations of the large-scale community and institutional dynamics of condensed matter physics in the United States focus primarily on this era of the Cold War.

Much of this literature examines specific institutional contexts. Because of the field’s diversity, individual institutions established solid state and condensed matter research programs with widely different emphases. Although the field was originally associated most strongly with the golden age of industrial laboratories at places like Bell, General Electric, Westinghouse, Corning, and RCA, solid state and condensed matter physics grew equally rapidly in industrial laboratories, academic physics departments, and government research facilities, not least the newly established National Laboratory system. Whereas one university or government facility might seek to put condensed matter physicists into conversation with chemists and engineers in order to encourage industrial development, as, for example, happened within the ARPA-funded system of interdisciplinary laboratories hosted on college campuses, others sought to emphasize the field’s fundamental intellectual potential.

Institutional structure dedicated to solid state physics (initially) and condensed matter physics (later), quickly grew in other countries as well following World War II. In each of the nations in which it took root, condensed matter physics reflected different economic conditions, political realities, and national priorities. For example, whereas “solid state physics” in the United States included work on liquids, molecules, and other substances that were not, strictly speaking, solids, “Festkörperphysik” in Germany, particularly East Germany, tended to be more narrowly focused on the physics of regular crystal lattices. And in France “physique du solide,” which grew in the late 1950s and early 1960s, did so alongside the better-established “chimie du solide,” which reflected the long tradition of French chemistry. The English-language literature treats the American context more extensively than it does other national contexts, but condensed matter physics was nevertheless a lively research area worldwide, especially during the Cold War. The sources below, though they do not offer the same depth of coverage of other countries as they do of the United States, are selected to convey a sense of the field’s international reach.

The institutional history of condensed matter physics is an exercise in identifying the local conditions that gave the field purpose and meaning. In addition to their intellectual and technical goals, condensed matter physicists actively pursued professional goals, and the pursuit of such goals had consequences for the way their research was organized. A considerable proportion of the existing historical literature focuses on the United States, but available resources nevertheless map out these dynamics in a variety of institutional and national contexts.

V. Social, Cultural, and Political Significance
The political history of condensed matter physics overlaps considerably with its institutional history, and so many of the sources listed in the previous section are also relevant here. But the social and cultural history of condensed matter physics are less thoroughly explored than its conceptual and institutional history. The social and cultural history of condensed matter physics also overlaps with its technological relevance, particularly in its role as a driver of consumer technologies. Social and cultural histories of technology, however, rarely discuss the scientific background of those technologies, and so the connection between condensed matter research and the devices and materials that populate modern life is not as strong as it could be, either in the historical literature or in the popular imagination. Historians have, however, addressed in some detail the influence of the distinctive political, cultural, and economic features of the Cold War on the way that condensed matter physics, or certain parts of it, developed.

The most prominent question in the current literature on the social and cultural significance of condensed matter physics is that of to what extent military patronage influenced the direction of the field. Solid state physics emerged as a distinct field in the United States at a time when the service agencies were investing considerable amounts of money in scientific research and development. Some historians emphasize the extent to which the interests of the defense establishment exerted pressure on physics, particularly condensed matter physics with its high degree of industrial relevance. Others have focused on the strategies that physicists deployed to pursue their own, curiosity-driven research within this context. The picture that emerges is a complex one, in which the strong social forces and funding incentives favoring defense-oriented goals meet and compete with strong-willed individuals who want to pursue their fundamental physical curiosity.

VI. Technological Applications
Condensed matter physics has had a long, but at times ambivalent relationship with technology. On one hand, the nature of research into the physical properties of materials often have evident commercial potential, ensuring consistent government funding and industrial interest. On the other hand, condensed matter physicists have often worried that both funders and the general public only see their work in terms of technological deliverables, and remain either ignorant of, or uninterested in the contributions condensed matter physics can make, and has made, to basic scientific understanding. This has meant that at certain points, condensed matter physicist have been motivated to advertise their role as the source of new technologies, whereas at other times they have sought to put some distance between their basic research activities and commercial interests.

This ambivalence aside, however, condensed matter physics has been a consistent contributor to the development and dissemination of the countless consumer technologies and industrial processes that have emerged since the end of World War II. The consumer electronics industry owes a particularly sizable debt to condensed matter research, but no less relevant are the improvement of materials for aviation, better understanding of fluid dynamics for infrastructure management, or research into soft-matter biomaterials for medical applications. The actual range of condensed matter physics’ technological contributions is significantly broader than the current literature can capture, but historians have documented the stories of many of these technologies, with a particular focus on semiconductor-based electronic devices, offering an account of how condensed matter physics connects to modern society through its applications.

VII. Directions for Future Research
Having reviewed the current state of the history of condensed matter physics, what remains to be done? The field is yet young, and myriad opportunities exist for both physicists and historians to help shape its growth. In closing, I consider a few potential growth areas in the conceptual, institutional, social, and technological history of condensed matter physics.

Despite the thorough mapping of early quantum studies of solids, many topics remain largely unexplored. Even this earlier era lacks systematic studies of the domain concept in magnetism and the role of digital computers in the rise of ab initio methods, to give just two examples. Later conceptual developments are even less well explored, in particular those dating from the late twentieth and early twenty first centuries, with the intellectual history of the physics of amorphous solids and soft matter, for example, awaiting detailed attention.

Strong historical treatments are available for condensed matter work at Bell Laboratories, many of the National Labs, and several key universities, and a range of national contexts, but the institutional picture requires fleshing out. The University of Illinois was an early center for solid state research, and the University of Chicago’s James Franck Institute became a condensed matter hub later in the twentieth century, for example. The need for a more thorough examination of condensed matter physics in industrial laboratories other the few that had the luxury of supporting basic research during the early Cold War is also evident. Solid state and condensed matter physics possessed a large industrial footprint, and most of the physicists working in industry were not at Bell, GE, or Westinghouse.

The vast majority of social, cultural, and political histories of physics in the twentieth century have focused on high energy physics, nuclear physics, and cosmology, and an array of opportunities exists to explore where condensed matter physics fits into those stories. Even though condensed matter physics has been and remains less visible to the public than its better-known sibling fields, it has been the largest field of physics for many decades. The ways in which solid state physics interacted with society, through technology, government advising, political advocacy, or other avenues holds the potential to significantly advance our historical understanding of the relationship between physics and the societies that support it.

The connections between condensed matter physics and consumer electronics have been thoroughly documented, and with good reason. But condensed matter physics has contributed to a much more varied array of technological developments. Much of the condensed matter work relevant to military applications, of course, remains classified. But histories can yet be written about the pathway between condensed matter physics and medical devices, the improved ceramic materials and glassware which were pressed into service in kitchens around the world and on spacecraft orbiting it, and the many scientific instruments that have hastened the development of condensed matter physics.
