Research
Our research aims to understand how interactions between many quantum particles give rise to emergent, collective phenomena that have no counterpart in individual constituents. We investigate strongly correlated quantum systems with interests ranging from quantum criticality and topological phases to lattice gauge theories, nonequilibrium dynamics, and many-body localization.
Addressing these problems requires both analytical insight and powerful computational techniques. We develop and employ tensor network algorithms alongside quantum field theory and different many-body techniques to study systems beyond the reach of conventional numerical approaches, while also drawing on concepts from quantum information theory to characterize complex quantum states.
A central theme of our research is quantum simulation using synthetic quantum systems. We explore how ultracold atoms, Rydberg atom arrays, trapped ions, and cavity QED platforms can realize exotic many-body Hamiltonians and provide experimentally accessible settings for studying fundamental problems in condensed matter physics and beyond.
