Matthias Troyer

from Wikipedia, the free encyclopedia

Matthias Troyer (born April 18, 1968 in Linz ) is an Austrian physicist.

Troyer (who received the gold medal at the 1986 International Chemistry Olympiad) studied physics at the University of Linz and the ETH Zurich , where he received his diploma in 1991 and his doctorate in 1994 under D. Würtz and TM Rice. The subject of the dissertation, which received the gold medal from ETH Zurich, was the numerical solution of fermions in low-dimensional systems. As a post-doctoral student he was a Fellow of the Japan Society for the Promotion of Science at the University of Tokyo and was an assistant at the ETH Zurich from 1998. In 2005 he became a professor.

He develops algorithms for the simulation of quantum mechanical many-body systems and investigated, among other things, quantum phase transitions, ultracold atomic gases, supersolidity of bosons, quantum magnets, quantum mechanical machines, strongly correlated electron systems. He initiated the open source project ALPS to make algorithms in many-body systems accessible to the scientific public.

He is a Fellow of the American Physical Society (2011). In 2004 he was a member of the Aspen Center for Physics, of which he has been a trustee since 2014.

In 2012 Troyer received an ERC Advanced Grant. In 2016 he received the Aneesur Rahman Prize for pioneering work in several apparently inaccessible areas of the quantum mechanical many-body problem and for making efficient, sophisticated computer programs accessible to the scientific community (laudation). For 2019, Troyer was awarded the Hamburg Prize for Theoretical Physics .
