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…
Immiscible to miscible quenching instabilities in two-dimensional binary Bose-Einstein condensates
Lauro Tomio, S. Sabari, Arnaldo Gammal +1
Immiscible to miscible quenching transitions (IMQT) in homogeneous Bose-Einstein condensate are investigated, considering rubidium isotopes Rb and Rb confined in a tw…
Stable Quantum Vortices in Lee-Huang-Yang Dipolar Superfluids
S. Sabari, R. Radha, Lauro Tomio +1
The nucleation and dynamics of vortices in the quasi-two-dimensional rotating dipolar Bose-Einstein condensate are explored by taking into account the Lee-Huang-Yang (LHY) correcti…
Modulational instability of inter-spin-orbit coupled Bose-Einstein condensates in deep optical lattice
R. Sasireka, S. Sabari, A. Uthayakumar +1
We present a comprehensive study of modulational instability (MI) in a binary Bose-Einstein condensate with spin-orbit coupling, confined to a deep optical lattice. The system is m…
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…
Vortices in Tunable Dipolar Bose-Einstein condensates with Attractive Interactions
S. Sabari, R. Sasireka, R. Radha +2
We investigate the formation of vortices in quasi-two-dimensional dipolar Bose-Einstein Condensates (BECs) through the interplay between two-body contact and long-ranged dipole-dip…
