Research interests

  • My research interests include strongly correlated systems in the ultracold gases in optical lattices. Previously I have looked at ground state phase diagrams in bosonic systems with different geometries using density matrix renormalization group (DMRG) and matrix product states (MPS) methods. I also studied the dynamics by quenching from one phase to another to one or more critical points and looking at the defects formed as a function of quench rate to find Kibble-Zurek like mechanism. I then moved on to fermionic Hubbard model with nearest neighbour interactions and look at the effects of spin and mass imbalance. Currently I am interested in non-equilibrium phenomena using dynamical mean-field theory (DMFT) and bosonic dynamics using time-dependent Gutzwiller and projection operator approaches.
