Multifunctional Materials
Our group's interests are in understanding and predicting coupled and intertwined phenomena in multifunctional materials. These can range from the coupling of spin and orbital degrees of freedom -- as happens in topological materials -- to interweaving of magnetic and lattice properties -- as is seen in magnetoelectric multiferroics. We use a combination of accurate quantum mechanical simulations and simplified models to theoretically study these coupled phenomena, employing a broad spectrum of numerical as well as analytical techniques. We extensively collaborate on these topics with our experimentalist colleagues across the globe.

Non-Hermitian Topology
We are interested in understanding the interplay of non-Hermiticity and topology in open quantum systems. One particularly intriguing direction is the exploration of exceptional points and their higher dimensional generalizations and potential ways to control them. We also devise analytical methods, numerical techniques and machine learning approaches to uncover the role of disorder and driving in these systems.
