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…
Transient and steady-state chaos in dissipative quantum systems
Debabrata Mondal, Lea F. Santos, S. Sinha
Dissipative quantum chaos plays a central role in the characterization and control of information scrambling, non-unitary evolution, and thermalization, but it still lacks a precis…
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…
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…
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…
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…
Quantum transitions, ergodicity, and quantum scars in the coupled top model
Debabrata Mondal, Sudip Sinha, S. Sinha
We consider an interacting collective spin model known as coupled top (CT), exhibiting a rich variety of phenomena related to quantum transitions, ergodicity, and formation of quan…
Dynamical route to ergodicity and quantum scarring in kicked coupled top
Debabrata Mondal, Sudip Sinha, Subhasis Sinha
Unlike classical system, understanding ergodicity from phase space mixing remains unclear for interacting quantum systems due to the absence of phase space trajectories. By conside…
