Phases, collective modes, and non-equilibrium dynamics of dissipative Rydberg atoms
S. Ray, S. Sinha, K. Sengupta
We use a density matrix formalism to study the equilibrium phases and non-equilibrium dynamics of a system of dissipative Rydberg atoms in an optical lattice within mean-field theo…
Optical Lattice Modulation Spectroscopy for Spin-orbit Coupled Bosons
Sangita De Sarkar, Rajdeep Sensarma, K. Sengupta
Interacting bosons with two "spin'' states in a lattice show novel superfluid-insulator phase transitions in the presence of spin-orbit coupling. Depending on the parameter regime,…
Role of trap-induced scales in non-equilibrium dynamics of strongly interacting trapped bosons
Anirban Dutta, Rajdeep Sensarma, K. Sengupta
We use a time-dependent hopping expansion technique to study the non-equilibrium dynamics of strongly interacting bosons in an optical lattice in the presence of a harmonic trap ch…
A projection operator approach to the Bose-Hubbard model
Anirban Dutta, C. Trefzger, K. Sengupta
We develop a projection operator formalism for studying both the zero temperature equilibrium phase diagram and the non-equilibrium dynamics of the Bose-Hubbard model. Our work, wh…
