I am a theoretical condensed matter physicist. Condensed matter physics is
a rapidly evolving field of research driven by the potential for technological application as well as the quest for fundamental understanding of nature. The broad aim of my research is to study novel properties of quantum many-body systems. My current research interests include monitored quantum systems, quantum entanglement in interacting systems, non-Fermi liquids, thermalization, many-body localization, many-body quantum chaos, and strongly correlated electronic systems such as twisted bilayer graphene.
I do not take summer, winter or in-semester interns or project students from outside Indian Institute of Science
