The study of quantum systems of many strongly interacting particles (such as bosons, fermions, and spins). Several physical phenomena at low temperatures arise out of the intricate interplay of quantum mechanics and strong correlations. Broadly, my research interests fall into the following categories:
Development and application of novel numerical algorithms for the quantum many body problem (tensor networks and quantum Monte Carlo)
Multi-scale modeling of quantum matter with effective Hamiltonians from "density matrix downfolding"
Mott insulators and "frustrated" magnets with a strong emphasis on experimentally relevant materials
Physics of dilution and disorder, especially in magnets
Quantum information and entanglement, mutual information and density matrix based metrics
