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…
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…
Formation of paired phases of bosons and their excitations in a square lattice
Manali Malakar, Sudip Sinha, S. Sinha
We investigate the formation of paired states of bosons in an optical lattice, namely, pair superfluid (PSF) and pair supersolid (PSS) in the presence of pair hopping as well as th…
