The 2022 John Bardeen Prize is awarded to Jörg Schmalian (Karlsruher Institute of Technology), Mohit Randeria, (The Ohio State University), and Peter Hirschfeld (University of Florida) “For pioneering theoretical work that has provided significant insights on the nature of superconductivity, its realization in strongly correlated systems, and experimental probes of unconventional superconductors.”

Citation for Jörg Schmalian:
For impactful, materials-based theoretical insights into unconventional superconductors across the periodic table including organic superconductors, cuprates, and pnictides, and for pioneering work on the effect of intertwined order as well as on a beyond-quasi-particle description of normal states for unconventional superconductivity.

Citation for Mohit Randeria:
For contributions to the theory of the BCS-BEC crossover, for providing theoretical understanding of angle-resolved photoemission experiments on superconducting and pseudo gap phases of the cuprate superconductors, and for providing rigorous bounds on the superconducting transition temperature in two-dimensional materials.

Citation for Peter Hirschfeld:
For elucidating the roles of electronic structure effects in unconventional superconductors, and for developing key insights connecting the nature of unconventional superconducting gaps to transport, penetration depth, and scanning tunneling microscopy experiments.

The JOHN BARDEEN PRIZE was established in 1991 by the organizers of the International Conference on the Materials and Mechanisms of Superconductivity (M2S) in honor of Dr. John Bardeen for “theoretical work that has provided significant insights on the nature of superconductivity and has led to verifiable predictions”.

1994 : Anthony J. Leggett, G. M. Eliashberg
for the development of the pairing theory to account for the thermodynamic and dynamic properties of strong coupling superconductors.

1991 : Vitaly L. Ginzburg, Alexei A. Abrikosov, Lev P. Gor’kov
for developing the GLAG theory which has proved the most useful tool to investigate superconductivity phenomenologically and, further, has also been playing a vital role in the studies of the high temperature superconductors.

John Bardeen (1908-1991) was an American physicist and electrical engineer, the only person to have won the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory.

The transistor revolutionized the electronics industry, allowing the Information Age to occur, and made possible the development of almost every modern electronic device, from telephones to computers to missiles. Bardeen’s developments in superconductivity, which won him his second Nobel, are used in Nuclear Magnetic Resonance Spectroscopy (NMR) or its medical sub-tool magnetic resonance imaging (MRI).

In 1990, John Bardeen appeared on LIFE Magazine’s list of “100 Most Influential Americans of the Century.”
