condensed matter and quantum information theory

One of my main interests centers on the physics of strongly interacting systems, where typical perturbative methods fail. High temperature and unconventional superconductors, lanthanide and actinide materials (often referred to as f-electron materials), quantum Hall systems, frustrated quantum magnets, multiferroics, ultracold atoms, and correlated topological quantum matter, are some examples of physical systems I focus on. My work includes, analysis and prediction of new physical phenomenon, organizing principles, and functionalities. To this end, I spend part of my research developing novel mathematical tools required to understand the panoply of emergent quantum orders and its non-equilibrium dynamics.

The quest to explore the ultimate limits and principles of quantum physics is out there. I am concerned with studying foundational, software, and hardware aspects of quantum information science. Simulation of physical phenomena using quantum devices is one of my areas of research. Developing new entangled quantum probes and interferometers to unveil exotic correlations in matter is another. I am also concerned with topics of potential overlap between my two research disciplines, where feedback from one field may help to resolve significant problems in the other. After all, a quantum information device is a quantum many-body system.
