Weakly interacting Bose gases in the canonical ensemble
Jonata S. Soares, Axel Pelster, Arnaldo Gammal
Based on the canonical description of a non-interacting Bose gas, we work out how both thermodynamic and statistical properties change perturbatively with respect to weak two-parti…
Negative Interaction Quench Dynamics of Density-Ordered Dipolar Bosons in a One-Dimensional Optical Lattice
Rhombik Roy, N. D. Chavda, Barnali Chakrabarti +1
We explore the nonequilibrium dynamics of a density-ordered dipolar Bose gas in a finite one-dimensional optical lattice following a negative interaction quench, using the numerica…
Entropy Signatures of Collective Modes and Vortex Dynamics in Rotating Two--Dimensional Bose--Einstein Condensates
L. A. Machado, N. D. Chavda, B. Chatterjee +4
We investigate the nonequilibrium dynamics of a two-dimensional rotating Bose gas confined in a symmetric anharmonic trap, employing the multiconfigurational time-dependent Hartree…
Dynamics of one-dimensional Bose-Josephson Junction in a Box Trap: From Coherent Oscillations to Many-Body Dephasing and Dynamical Freezing
Abhik Kumar Saha, L. F. Calazans de Brito, Rhombik Roy +4
Understanding how coherent quantum dynamics give way to correlation-dominated behavior in low-dimensional systems remains a central challenge in quantum many-body physics. Here, we…
Stability of dark solitons in a bubble Bose-Einstein condensate
Raphael Wictky Sallatti, Lauro Tomio, Dmitry Pelinovsky +1
The stability of nonlinear waves on curved surfaces is a problem of widespread interest across physics. Here, we establish the stability criteria for dark solitons on a spherical B…
Rayleigh-Taylor, Kelvin-Helmholtz and immiscible to miscible quenching instabilities in binary Bose-Einstein condensates
R. Kishor Kumar, S. Sabari, Arnaldo Gammal +1
We investigate three kinds of instabilities in binary immiscible homogeneous Bose-Einstein condensate, considering rubidium isotopes Rb and Rb confined in two-dimensi…
