I have studied different strongly correlated problems in condensed matter physics. In general, I’m interested in the search for new states of matter, anomalous responses in them, and in the general area of phase transitions and critical phenomena that arise from micro-scale many body interactions. This area covers a very large spectrum of physical systems that includes cooperative phenomena in ultracold atomic gases, exotic magnetic orderings in magnetic metals where itinerant electrons and localized magnetic moments are correlated each other, spin and orbital orderings in transition metal oxides, magnetic field induced coexistence of magnetism and superconductivity, quantum magnetism in frustrated Mott insulators, magnetoelectric effect in antiferromagnets, and chiral spin liquid transition in three dimension. In general, I approached these problems by combining numerical techniques, such as quantum and classical Monte-Carlo methods, with the analytical methods that were appropriate for each specific problem.
