Condensed matter physics is a branch of physics that studies the macroscopic and microscopic physical properties of matter in condensed phases, especially solids and liquids. It connects experimental observations with theoretical models to explain emergent behavior in systems with many interacting degrees of freedom. Research in this field has driven major advances in materials science, electronics, quantum information, and industrial technologies.

History

The discipline emerged from nineteenth- and early-twentieth-century work linking thermodynamics and statistical mechanics with the properties of materials studied at institutions such as the Cavendish Laboratory and Bell Labs. Key milestones include the development of quantum theory by figures associated with University of Cambridge, University of Göttingen, and Institute for Advanced Study, and the formulation of theories at centers like Los Alamos National Laboratory and IBM Research. Seminal contributions came from researchers honored by the Nobel Prize in Physics and Wolf Prize in Physics, with landmark results such as the theory of superconductivity by John Bardeen and collaborators and the theory of electron localization by Philip Anderson. Postwar expansion at universities including Massachusetts Institute of Technology, Stanford University, and Harvard University fostered growth in thin films, semiconductors, and low-temperature physics, leading to discoveries recognized at venues such as the Buckley Prize.

Fundamental concepts

Condensed matter physics relies on principles developed across traditions centered at laboratories like the Max Planck Institute for Solid State Research and departments like University of Oxford, invoking quantum mechanics from pioneers connected to Niels Bohr, Paul Dirac, and Enrico Fermi. Central concepts include band theory developed in the spirit of work at University of Cambridge and ETH Zurich, quasiparticles informed by Landau's ideas from Lev Landau, symmetry breaking with connections to theoretical efforts at CERN, and phase transitions conceptualized in contexts highlighted by the Landau theory lineage. Notions such as Fermi surfaces, phonons, magnons, and collective excitations are framed using methods from students and collaborators affiliated with Princeton University, Columbia University, and California Institute of Technology.

Experimental techniques

Experimental progress has been driven by instrumentation cultivated at places like Bell Labs and Los Alamos National Laboratory, employing tools such as x-ray diffraction developed from traditions at Royal Institution, scanning probe methods that trace to laboratories associated with IBM Research, neutron scattering conducted at facilities like Oak Ridge National Laboratory, and electron microscopy refined at institutions including University of Cambridge. Low-temperature platforms used at Argonne National Laboratory and Kavli Institute enable studies of superconductivity and quantum Hall effects, while synchrotron sources operated by organizations such as the European Synchrotron Radiation Facility support spectroscopy, angle-resolved photoemission, and imaging pioneered by teams at Stanford University and University of Oxford.

Theoretical frameworks

The field synthesizes theoretical approaches developed by researchers affiliated with institutions such as Princeton University, Harvard University, and Max Planck Society. Many-body theory, diagrammatic techniques, and renormalization group methods emerged through collaborations linked to CERN and University of Chicago. Density functional theory, advanced at Rutgers University and University of California, Berkeley, enables ab initio predictions of electronic structure, while topological band theory and symmetry-protected phases reflect conceptual advances recognized by awards like the Nobel Prize in Physics. Computational frameworks implemented on supercomputers at Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory complement analytic models from groups at Columbia University and Yale University.

Subfields and phenomena

Research spans subfields with institutional roots at places such as IBM Research, Bell Labs, and Max Planck Institute for Solid State Research: electronic materials and semiconductors that trace to Bell Labs and Fairchild Semiconductor; superconductivity with legacies at University of Cambridge and Argonne National Laboratory; magnetism explored at Los Alamos National Laboratory and Indiana University; and low-dimensional systems advanced by groups at Stanford University and University of California, Santa Barbara. Additional areas include topological insulators and quantum anomalous Hall phenomena studied at Princeton University and University of Tokyo, strongly correlated electron systems pursued at Cornell University and University of Illinois Urbana-Champaign, and soft condensed matter and biological materials investigated at Massachusetts Institute of Technology and Harvard University.

Applications and technologies

Condensed matter physics underlies technologies developed through collaborations between academia and industry, for example semiconductors from companies linked to Fairchild Semiconductor and Intel Corporation, magnetic storage advanced with input from IBM Research, and superconducting devices emerging from Hypertech Research-style partnerships. Quantum materials research informs quantum computing platforms built by organizations such as Google and Microsoft Research, while thin-film and nanofabrication methods refined at Stanford University and University of Cambridge support microelectronics and optoelectronics used by firms like Samsung and Sony. Advances recognized by awards and institutions including the Nobel Prize in Physics continue to translate fundamental discoveries into sensors, energy materials, and emerging devices commercialized through technology transfer offices at universities such as MIT and Oxford University.
