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…
Spin-orbit coupled spin-boson model : A variational analysis
Sudip Sinha, Subhasis Sinha, Sushanta Dattagupta
The spin-boson (SB) model is a standard prototype for quantum dissipation, which we generalize in this work, to explore the dissipative effects on a one-dimensional spin-orbit (SO)…
Supersolid phases of bosons
Sudip Sinha, S. Sinha
Supersolids--the enigmatic phase of quantum matter, with properties resembling both the superfluid and solid states--have been actively sought over the past 70 years. We provide a…
Exploring the properties of quantum scars in a toy model
Sudip Sinha, S. Sinha
We introduce the concept of ergodicity and explore its deviation caused by quantum scars in an isolated quantum system, employing a pedagogical approach based on a toy model. Quant…
