Emergence of giant vortices under nonlinear rotation with attractive interactions in a toroidal condensate
Rony Boral, Swarup K. Sarkar, Matthew Edmonds +2
We numerically investigate the effects of a density-dependent gauge potential which induces nonlinear rotation on a Bose-Einstein condensate confined in a toroidal trapping geometr…
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
P. Raman, R. Radha, Pankaj K. 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…
Vortex Retention Mediated Turbulent Transitions in Self-Gravitating Bosonic and Axionic Condensates
Anirudh Sivakumar, Sanjay Shukla, Rahul Pandit +2
We investigate turbulent spin-down dynamics in self-gravitating Bose-Einstein condensates, comparing purely bosonic and axionic (higher-order interacting) systems. Through simulati…
Anomalous Energy Injection in the Gross-Pitaevskii Framework for Turbulence in Neutron Star Glitches
Anirudh Sivakumar, Pankaj Kumar Mishra, Ahmad A. Hujeirat +1
Neutron star glitches -- sudden increases in rotational frequency -- are thought to result from angular momentum transfer via quantized vortices in the superfluid core. To investig…
Supersolid phases and collective excitations in two-dimensional Rashba spin-orbit coupled spin-1 condensates
Sanu Kumar Gangwar, Sayan Chatterjee, Rajamanickam Ravisankar +3
We investigate the collective excitation spectrum and dynamics of a quasi two-dimensional spin-1 Bose-Einstein condensate with Rashba type spin-orbit (SO) coupling. Employing Bogol…
