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…
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…
Dissipative chaos and steady state of open Tavis-Cummings dimer
Debabrata Mondal, Andrey Kolovsky, S. Sinha
We consider a coupled atom-photon system described by the Tavis-Cummings dimer (two coupled cavities) in the presence of photon loss and atomic pumping, to investigate the quantum…
Self-trapping phenomenon, multistability and chaos in open anisotropic Dicke dimer
G. Vivek, Debabrata Mondal, Subhadeep Chakraborty +1
We investigate semiclassical dynamics of a coupled atom-photon interacting system described by a dimer of anisotropic Dicke model in the presence of photon loss, exhibiting a rich…
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…
Impurities in quasi-one-dimensional droplets of binary Bose mixtures
Sudip Sinha, Sayak Biswas, L. Santos +1
Recently created self-bound quantum droplets of binary Bose mixtures open intriguing possibilities for the study of impurity physics. We show that the properties of impurities embe…
Finite temperature phases and excitations of bosons on a square lattice: A cluster mean field study
Manali Malakar, Sudip Sinha, S. Sinha
We study the finite temperature phases and collective excitations of hardcore as well as softcore bosons on a square lattice with nearest and next nearest neighbor interactions, fo…
