Computational Physics Group

torus spectroscopy

Our group is interested in the theoretical and computational exploration of correlated quantum matter in condensed matter and AMO systems. We strive to understand novel phases of matter, quantum critical phenomena and quantum systems out of equilibrium. Our research builds on a blend of concepts and ideas from condensed matter theory, statistical mechanics, quantum field theory and quantum information. We also develop and implement innovative computational algorithms in order to perform large-scale computer simulations on high-performance computers.

Our group was previously hosted at the University of Innsbruck (2011-2021) and the corresponding webpage can be found here. The group will now be located both at the Paul Scherrer Institute and at the LLTCP Lab at EPFL.
