Jürg Martin Fröhlich (born 4 July 1946 in
theoretical physicist. He is best known for introducing rigorous techniques for the analysis of statistical mechanics models, in particular continuous symmetry breaking (infrared bounds),[1] and for pioneering the study of topological phases of matter using low-energy effective field theories.[2]
Biography
In 1965 Fröhlich began to study mathematics and physics at
Eidgenössischen Technischen Hochschule Zürich. In 1969, under Klaus Hepp and Robert Schrader, he attained the Diplom (“Dressing Transformations in Quantum Field Theory”), and in 1972 he earned a PhD from the same institution under Klaus Hepp. After postdoctoral visits to the University of Geneva and Harvard University (with Arthur Jaffe), he took an assistant professorship in 1974 in the mathematics department of Princeton University. From 1978 until 1982 he was a professor at Institut des Hautes Études Scientifiques in Bures-sur-Yvette
in Paris, and since 1982 he has been a professor for theoretical physics at ETH, where he founded the Center for Theoretical Studies.
Over the course of his career, Fröhlich has worked on
non-commutative geometry
.
Honors and awards
In 1991 he received with
FQHE, Chern–Simons Theory and Integral Lattices”). He also co-authored a book[4] on quantum triviality. In 2020, he was elected international member of the National Academy of Sciences.[5]
