Pieter W. Claeys



I am a B.A.E.F. postdoctoral fellow with a Francqui Fellowship currently located at Boston University. My research is situated in the field of quantum many-body systems, focusing on the properties of integrable models and their applications away from integrability in both stationary and dynamic systems.

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