William Halperin

from Wikipedia, the free encyclopedia

William Paul Halperin (born July 16, 1945 in Ottawa ) is a Canadian-American experimental low-temperature physicist.

Halperin graduated from Queen's University (Kingston) with a bachelor's degree in 1967 and the University of Toronto with a master's degree in 1968. He received his doctorate in physics from Cornell University in 1975 . In 1975 he became Assistant Professor and 1986 Professor at Northwestern University and was from 2001 John Evans Professor . From 1990 to 1995 he headed the Faculty of Physics and Astronomy. He was also at the Argonne National Laboratory .

He deals with superfluid helium 3, superconductivity , NMR spectroscopy of high-temperature superconductors (including very high magnetic fields in the National High Magnetic Field Laboratory in Tallahassee) and liquid transport in porous media.

In 2017 he and his theoretician colleague James Sauls from Northwestern University (with whom he works a lot) and Jeevak Parpia from Cornell University received the Fritz London Memorial Prize for the investigation of disorder in superfluid helium 3 and the insights into its complexities that it enabled Symmetry breaking behavior.

He is a US citizen. Halpern is a Fellow of the American Physical Society . In 1977 he was a Sloan Research Fellow and he was a Yamada Science Foundation Fellow. He is the editor of Progress in Low-Temperature Physics.
