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…

Chaotic dynamics of Bose-Einstein condensates in a tilted optical lattice

C. Selvaraju, S. Sabari, O. T. Lekeufack +2

This study investigates the emergence of chaotic dynamics in Bose-Einstein condensates (BECs) subjected to both alternating (AC) and constant (DC) components of the interaction str…

Controlling second-order rogue matter wave and line bright soliton dynamics in 2D Bose-Einstein Condensate with higher-order interactions and gain/loss atoms

C. E. Nkenfack, O. T. Lekeufack, S. Sabari +2

We investigate the two-dimensional modified Gross-Pitaevskii equation, accounting for the effects of atom gain/loss and a time-independent isotropic confining potential, utilizing…
