Stability and dynamics of dark-bright solitons in spin-orbit- and Rabi-coupled binary Bose-Einstein condensates
K. Rajaswathi, R. Ravisankar, R. Radha +2
We investigate the stability and nonlinear dynamics of dark--bright solitons in a one-dimensional binary Bose--Einstein condensate subjected to synthetic spin--orbit and Rabi coupl…
Dynamically Stable Vortices in Exciton-Polariton Condensates Engineered by Repulsive Interactions
Palanivel Raman, Ramaswamy Radha, Pankaj Kumar Mishra +1
We present an analytical and numerical study of the dynamics and stability of exciton-polariton condensates described by the open-dissipative Gross-Pitaevskii equation, incorporati…
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…
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…
Role of higher-order interactions on the modulational instability of Bose-Einstein condensate trapped in a periodic optical lattice
S. Sabari, OT. Lekeufack, SB. Yamgoue +2
In this paper, we investigate the impact of higher-order interactions on the modulational instability (MI) of Bose-Einstein Condensates (BECs) immersed in an optical lattice potent…
