Martin Lüscher

Martin Lüscher ( born August 3, 1949 in Bern ) is a Swiss theoretical physicist who deals mainly with numerical quantum chromodynamics ( lattice gauge theory).

Lüscher studied at the University of Bern and in Hamburg, where he received his doctorate. He worked from the 1970s at DESY in Hamburg and was in Hamburg professor of theoretical physics. Since 1999 he has been at CERN.

Lüscher is one of the driving forces in the development of " quantum chromodynamics on the lattice ". Among other things he found in 1991 with Peter Weisz and Ulrich Wolff a new recursive method which avoids large lattice and studies on many length scales allows (Non Perturbative Renormalization - Group). In the 1980s he developed Weisz "improved actions" for lattice gauge theories ( in which a plurality of lattice variants of the continuum effects is used), which have better convergence properties in the continuum limit.

In 2000 he received the Max Planck Medal of the German Physical Society and the 2004 Heinrich Greinacher Prize of the University of Bern.
