Emergence of a quasi-ergodic steady state in a dissipative Tavis-Cummings array
Debabrata Mondal, K. Sengupta, Subhasis Sinha
In an atom-photon interacting system described by Tavis Cummings Hubbard (TCH) model, we demonstrate the emergence of a quasi-steady state in a dissipative environment that exhibit…
Quantum droplets and condensates in an optical lattice coupled to a dissipative cavity: Collective excitations and non-equilibrium dynamics
G. Vivek, Sudip Sinha, Subhasis Sinha
Motivated by recent experiments on light-matter interacting systems, we investigate a dilute Bose gas and self-bound quantum droplets in a one-dimensional optical lattice coupled t…
Dissipation-induced symmetry breaking: Emphanitic transitions in lead- and tin-containing chalcogenides and halide perovskites
Kingshuk Mukhuti, Sudip Sinha, Subhasis Sinha +1
Lead and tin-based chalcogenide semiconductors like PbTe or SnSe have long been known to exhibit an unusually low thermal conductivity that makes them very attractive thermoelectri…
Classical route to ergodicity and scarring in collective quantum systems
Sudip Sinha, Sayak Ray, Subhasis Sinha
Ergodicity, a fundamental concept in statistical mechanics, is not yet a fully understood phenomena for closed quantum systems, particularly its connection with the underlying chao…
Quantum fluctuations in quasi-one-dimensional dipolar Bose-Einstein condensates
Daniel Edler, Chinmayee Mishra, Falk Wächtler +3
Recent experiments have revealed that beyond-mean-field corrections are much more relevant in weakly-interacting dipolar condensates than in their non-dipolar counterparts. We show…
Classical route to ergodicity and scarring phenomena in a two-component Bose-Josephson junction
Debabrata Mondal, Sudip Sinha, Sayak Ray +2
We consider a Bose-Josephson junction (BJJ) formed by a binary mixture of ultracold atoms to investigate the manifestation of coherent collective dynamics on ergodicity and quantum…
