Pieter W. Claeys



Postdoctoral researcher at the Cavendish Laboratory at the University of Cambridge, after having previously been a B.A.E.F. postdoctoral fellow at Boston University and an FWO Ph.D. fellow at Ghent University and the University of Amsterdam. My research focuses on the mathematical and physical aspects of quantum many-body theory.

Keywords: Strongly interacting quantum many-body systems, condensed matter physics, mathematical physics, (broken) integrability, Floquet dynamics
