Pierre Hohenberg (3 October 1934 – 15 December 2017) was a French-American theoretical physicist, who worked primarily on statistical mechanics.[2]
The Hohenberg-Kohn theorems, formulated by Hohenberg and Walter Kohn gave rise to the density functional theory (DFT). He is also known for the development of dynamic scaling theory of critical phenomena, along with Bertrand Halperin.[3]
Academic life
Pierre Claude Hohenberg studied at Harvard University, where he earned his bachelor's degree in 1956 and a master's degree in 1958 (after a stay during 1956/57 at École Normale Supérieure), and his doctorate in 1962.[2]
From 1962 to 1963, he was at the Institute for Physical Problems in Moscow, followed by a stay at the École Normale Supérieure in Paris.
From 1964 to 1995 he was at Bell Laboratories in Murray Hill.
From 1985 to 1989, he was director of the department of theoretical physics and from 1989 to 1995 was "Distinguished Member of Technical Staff".
From 1974 to 1977, he was also professor of theoretical physics at the TU München, where he had previously been a 1972–1973 guest professor.
From 1995 to 2003 he was "Deputy Provost of Science and Technology" at Yale University.
Subsequently, he was the Yale "Eugene Higgins Adjunct Professor of Physics and Applied Physics".
Hohenberg was additionally from 1963 to 1964 and again in 1988 guest professor in Paris and in 1990–1991 a Lorentz-Professor in Leiden.
In 2004 he became Senior Vice Provost of Research at New York University, a position held until 2011, when he stepped down to join the Physics Department as Professor.
In 2012 he became Emeritus Professor of Physics at NYU.[2]
Research
Hohenberg formulated in 1964 with Walter Kohn the Hohenberg–Kohn theorem in the course of his work on density functional theory.
He became famous primarily for his investigations in the 1960s and 1970s in the theory of dynamic (i.e. temporally variable) critical phenomena close to phase transitions. He collaborated thereby with Bertrand Halperin, Shang-keng Ma and Eric Siggia in the application of renormalization methods. Additionally, Hohenberg worked (with Swift) on hydrodynamic instabilities, on the Swift–Hohenberg equation and on pattern formation in non-equilibrium systems with Michael Cross. Preceding David Mermin and Herbert Wagner he proved in 1967 the impossibility of spontaneous symmetry breaking in one and two dimensions. With N. Richard Werthamer, Eugene Helfand, Hohenberg came up with the Werthamer–Helfand–Hohenberg theory in 1966 to model type-II superconductors.[4] In collaboration with Richard Friedberg, he presented a new formulation of nonrelativistic quantum mechanics based on the consistent histories approach to the interpretation of quantum mechanics.
Fellowships and awards
Hohenberg was also politically active. In 1983, he chaired the committee of the American Physical Society for the freedom of scientists and in 1992–1993 on an APS committee for the support of scientists in the Soviet Union. From 1984 to 1996, he was a member of the committee for human rights of the New York Academy of Sciences. Hohenberg was a fellow of the American Academy of Arts and Sciences (since 1985),[2] the National Academy of Sciences (from 1989),[5] the American Philosophical Society (since 2014)[3] and the New York Institute for the Humanities (since 2016).[citation needed]
He received several prizes including
Hobbies
An accomplished continuous distance swimmer, Hohenberg in the second decade of the 21st century annually contested the artist/writer Richard Kostelanetz in a one-hour race at the NYU Coles pool until the pool was closed.
Usually they declare a draw.[citation needed]
