When solid state physics emerged in the 1940s, its name was controversial. By the 1970s, some physicists came to prefer “condensed matter” as a way to identify the discipline of physics examining complex matter. Physicists and historians often gloss this transition as a simple rebranding of a problematically named field, but attention to the motives behind these names reveals telling nuances. “Solid state physics” and “condensed matter physics”—along with “materials science,” which also emerged during the Cold War—were named in accordance with ideological commitments about the identity of physics. Historians, therefore, can profitably understand solid state and condensed matter physics as distinct disciplines. Condensed matter, rather than being continuous with solid state physics, should be considered alongside materials science as an outlet for specific frustrations with the way solid state was organized.

The agency’s name vacillated between ARPA and DARPA (Defense Advanced Research Projects Agency) as the agency underwent sinusoidal acknowledgement of its focus on military research. To avoid confusion, I refer to it as ARPA throughout. For reference, it was founded as ARPA in 1958, changed its name to DARPA in 1972, dropped the “D” in 1993, and restored it in 1996.
In 1975, this journal was absorbed into Zeitschrift für Physik when the latter split into two sections, the second of which was devoted to condensed matter and general physics.
Common lore holds that Anderson and Volker Heine coined “condensed matter” in 1967 while Anderson was a visitor in Cambridge and they changed the name of the solid state theory group at the Cavendish Laboratory to “theory of condensed matter.” Earlier occurrences of the term, in particular in the Springer journal title, belie this simple origin story, but the adoption of the term by a major UK research unit no doubt raised its profile in the Anglophone world.

Darrow wrote Van Vleck to coordinate nominating Eugene Wigner for fellowship in the American Philosophical Society: “Amor Germanorum, rum cum coca cola, et debilitas memoriae sunt radices multorum malorum. Sicut recte dixisti, Wigner non est socius noster in Societate Philosophica Americana.” (“Love of the Germans, rum and Coca-Cola, and weakness of memory are the roots of many evils.

Darrow was a visiting professor at Smith College in 1941. Van Vleck paid a visit, misplacing a pair of suspenders. The two exchanged a series of letters wondering if suspenders could be had in Smith colors and whether this reflected sartorial trends in seven sisters schools.

Seitz became a major figure in American solid state physics before transitioning to administrative and advisory roles in the 1950s.

Scott Knowles and Stuart Leslie have argued that the campuses at industrial laboratories such as Bell, General Motors, and IBM mimicked what architect Eero Saarinen supposed to be the university model of organizing research, namely a linear model, in which basic research fed directly into industrial applications. The rhetoric around MIT’s IDL reveal similar goals by suggesting that placing basic research in physics and chemistry alongside materials engineering fields would help to advance ARPA’s technical aims.

The implication that it was problematic to see physics as classifiable by states of matter was apropos. For instance, John Van Vleck’s 1932 monograph The Theory of Electric and Magnetic Susceptibilities (Oxford: Clarendon Press, 1932) was seen as a classic of solid state physics, even though it dealt mainly with magnetic susceptibilities in gasses. See: Midwinter and Janssen, “Kuhn Losses Regained” (ref. 21).

The ratio is starker in AIP journals, with 33 instances of “condensed matter” and 4,695 of “solid state.” The difference here is amplified by several factors, including the applied focus of AIP journals during an era that witnessed an explosion in topics such as solid state masers and lasers and the fact that the AIP search algorithm includes the titles of citing articles, which generates a high rate of false positives.
