My research interests include quantum information, quantum chaos, and the connections between the two. Even after a century of the advent of quantum mechanics, quantum-classical correspondence in nonintegrable chaotic systems still remains partially understood. Defining a notion of quantum chaos in many-body systems is even trickier due to the absence of a direct classical analog of these systems governed by Hamilton's equations of motion. In the last couple of decades, ideas and tools from quantum information theory have been widely employed towards the understanding of quantum chaos and quantum-classical correspondence. One of the goals of my research is to rigorously analyze these quantum-information theoretic measures being employed as indicators of quantum chaos. My second goal is to gain a deeper understanding and insight into nonintegrability in many-body systems to analyze whether nonintegrability would always imply chaos in many-body quantum systems or not.
