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…
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…
Chaos and quantum scars in a coupled top model
Debabrata Mondal, Sudip Sinha, S. Sinha
We consider a coupled top model describing two interacting large spins, which is studied semiclassically as well as quantum mechanically. This model exhibits variety of interesting…
Chaos and quantum scars in Bose-Josephson junction coupled to a bosonic mode
Sudip Sinha, S. Sinha
We consider a model describing Bose-Josephson junction (BJJ) coupled to a single bosonic mode exhibiting quantum phase transition (QPT). Onset of chaos above QPT is observed from s…
Dissipative Bose-Josephson junction coupled to bosonic baths
Sudip Sinha, S. Sinha
We investigate the effect of dissipation in a Bose-Josephson junction (BJJ) coupled to bath of bosons at two sites. Apart from the dynamical transition due to repulsive interaction…
