One-Dimensional Quench Dynamics in an Optical Lattice: sine-Gordon and Bose-Hubbard Descriptions
Subhrajyoti Roy, Rhombik Roy, Andrea Trombettoni +2
We investigate the dynamics of one-dimensional interacting bosons in an optical lattice after a sudden quench in the Bose-Hubbard (BH) and sine-Gordon (SG) regimes. While in higher…

Rotation quenches in trapped bosonic systems
Rhombik Roy, Sunayana Dutta, Ofir E. Alon
The ground state properties of strongly rotating bosons confined in an asymmetric anharmonic potential exhibit a split density distribution. However, the out-of-equilibrium dynamic…

Quench dynamics of 1D Bose gas in an optical lattice: does the system relax?
S. Bera, R Roy, A. Gammal +2
Understanding the relaxation process is the most important unsolved problem in non-equilibrium quantum physics. Current understanding primarily concerns on if and how an isolated q…
