Research Interests:
My research interest is in the field of quantum phase transitions in strongly correlated systems. It involves the phase transition in system of ultracold atoms(boson, fermions and Bose-Fermi mxiture) in optical lattice and superlattice, supersolids, phase transitions in frustrated systems, disordered induced phase transitions, ultracold molecules and non-equilibrium dynamics.
Research work: Ultracold atoms and molecules in optical lattice, supersolidity, frustrated and flatband systems, artificial magnetism, binary mixtures.
