Hidden Ergodic Relaxation in the Quench Dynamics of a Bichromatic Mott Lattice
Áttis V. M. Marino, Rhombik Roy, M. A. Caracanhas +5
We investigate the nonequilibrium dynamics of strongly interacting bosons in a finite bichromatic Mott lattice following a sudden quench of the secondary lattice amplitude. The coe…
Inferring rotations using a bosonic Josephson junction
Rhombik Roy, Ofir E. Alon
Rotation and quantum tunneling are fundamental concepts in physics, and their interplay in the ultracold atomic systems is of particular interest. In this theoretical work, we expl…
Dynamics and transport of Bose-Einstein condensates in bent potentials
Rhombik Roy, Ofir E Alon
The dynamics of bosons in curved geometries have recently attracted significant interest in quantum many-body physics. Leveraging recent experimental advances in tailored trapping…
Interplay of asymmetry and fragmentation in the many-body tunneling dynamics of two-dimensional bosonic Josephson junctions
Anal Bhowmik, Rhombik Roy, Sudip Kumar Haldar
It is well known that the many-body tunneling of a bosonic condensate leads to (longitudinal) fragmentation along the tunneling direction. In this work, we prepare the initial grou…
