Luttinger, 1963 in Copenhagen

Joaquin Mazdak Luttinger , called Quin, (born December 2, 1923 in New York City , † April 6, 1997 ibid) was an American theoretical physicist who dealt with many-particle problems in solid-state physics.

Luttinger studied at the Massachusetts Institute of Technology , where he received his bachelor's degree in 1942 and his doctorate in 1947 (on antiferromagnetism ). As a post-doctoral he became a Fellow of the National Research Council to Wolfgang Pauli to Zurich , where he met with, sometimes in collaboration with Res Jost , with quantum electrodynamics employed and 1948 (independently and simultaneously with Julian Schwinger ) the anomalous magnetic moment calculated the electron . In 1949/50 he was a Jewell Fellow at the Institute for Advanced Study . From 1950 to 1953 he was professor at the University of Wisconsin and, after intermediate positions, from 1953 at the University of Michigan and from 1958 at the University of Pennsylvania from 1960 professor at Columbia University , where he was chairman of the physics faculty from 1977 to 1980 and retired in 1993 . In 1957/58 he was visiting professor at the École normal supérieure and in 1967/68 and 1975/76 at Rockefeller University and from 1953 to the 1970s he was a frequent visiting scientist at Bell Laboratories. He died of complications from his bone marrow cancer.

He is known for the introduction of the Luttinger fluids (one-dimensional, interacting Fermi fluids , which, however, behave differently than traditional Fermi fluids in three dimensions) and his contributions to the theory of Fermi fluids , in particular the justification of the land theory of Fermi fluids . He also treated the De Haas van Alphen effect for interacting electrons. Lutting's theorem states that the volume enclosed by the Fermi surface depends only on the number of electrons when electrons interact in an external potential, regardless of the interaction. With Kohn he demonstrated superconductivity for fermion systems in three dimensions with repulsive interaction, with which they demonstrated that superconductivity was also possible without phonon interaction.

He worked with Walter Kohn (at Bell Labs as early as the 1950s, where their influential work on the theory of the effective mass of electrons in semiconductors helped Bell Labs set up a permanent theory department), Philippe Nozières , Philip Warren Anderson , John Clive Ward and Conyers Herring together.

In 1953 he became a Fellow of the American Physical Society . In 1976 he was elected a member of the National Academy of Sciences and in 1980 of the American Academy of Arts and Sciences .
