Research

Ultracold atoms - Bosons & Fermions – Investigation of static and dynamical properties of binary mixtures of quantum degenerate gases, dipolar condensates, and spinor Bose-Einstein condensates (BECs); quantum hydrodynamics and fluid instabilities in BECs; quantum Monte-Carlo simulations of ultracold quantum gases; BEC-BCS crossover in strongly interacting Fermi gases; and quantum turbulence in condensates.

Quantum degenerate Gases at Finite Temperatures – Study of quantum and thermal fluctuations in quantum Bose gases based on Hartree-Fock-Bogoliubov theory with Popov approximation and stochastic methods

Solitons and vortices – Study of formation and dynamics of topological defects like solitons and vortices in quantum fluids and instabilities associated with these topological defects.

Spin-orbit coupled superfluids – Investigation of spin-orbit coupled superfluid gases at zero and finite temperatures. Study of phase-separation, self-trapped states, spontaneous symmetry breaking, dynamical instabilities, and topological defects in spin-orbit-coupled BECs

Currently, we are working on a few problems related to the excitation spectrum of spin-orbital-angular-momentum-coupled spinor BECs, the fate of supersolidity in Raman-induced spin-orbit-coupled BECs, and the sudden quench dynamics in these systems.
