Shenglong Xu's research interests focus on theoretical condensed matter physics and quantum physics. He studies quantum phenomena of many-body systems (solid-state systems, ultra-cold atoms, quantum circuits, etc.) in and out of equilibrium, topics including quantum phase transitions and entanglement, quantum information scrambling, quantum thermalization, many-body localization, quantum scars. His research employs a combination of analytical methods and various numerical tools, such as quantum Monte Carlo, tensor network, and machine-learning. He is also interested in developing new tools to simulate quantum many-body systems.
