Emergence of spin-mixed superstripe phases in spin-orbit coupled spin-1 condensate
Sanu Kumar Gangwar, Rajamanickam Ravisankar, Paulsamy Muruganandam +1
We numerically investigate the ground state phases and quench dynamics of spin-orbit coupled spin-1 Bose-Einstein condensates with ferromagnetic and antiferromagnetic interactions.…
Collective excitation spectra of dipolar bosonic fractional quantum Hall states
Moumita Indra, Pankaj Kumar Mishra
We numerically investigate the collective excitation of spin-conserving and spin-reversed configuration of rotating diluted ultra-cold dipolar Bose gas. Rotating trapped Bose gas p…
Stable supersolids and boselets in spin-orbit-coupled Bose-Einstein condensates with three-body interactions
Rajamanickam Ravisankar, Sanu Kumar Gangwar, Henrique Fabrelli +6
We explore the stability of supersolid striped waves, plane-wave boselets, and other extended states in one-dimensional spin-orbit-coupled Bose-Einstein condensates with repulsive…
Rabi-induced localization and resonant delocalization of a binary condensate in a spin-asymmetric quasiperiodic potential
Swarup K. Sarkar, Sh. Mardonov, E. Ya. Sherman +1
We theoretically investigate the ground state and dynamics of a Rabi-coupled pseudospin-1/2 Bose-Einstein condensate, where only one spin component is subjected to an external pote…
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…
Excitation spectrum of vortex-lattice modes in a rotating condensate with a density-dependent gauge potential
Rony Boral, Swarup K. Sarkar, Matthew Edmonds +2
We investigate the collective excitation spectrum of a quasi-2D Bose-Einstein condensate trapped in a harmonic confinement with nonlinear rotation induced by a density-dependent ga…
Double unstable avoided crossings and complex domain patterns formation in spin-orbit coupled spin-1 condensates
Sanu Kumar Gangwar, Rajamanickam Ravisankar, Henrique Fabrelli +2
We analyze the impact of spin-orbit and Rabi couplings on the dynamical stability of spin-orbit-coupled spin-1 Bose-Einstein condensates for ferromagnetic (FM) and antiferromagneti…
Revealing turbulent Dark Matter via merging of self-Gravitating condensates
Anirudh Sivakumar, Pankaj Kumar Mishra, Ahmad A. Hujeirat +1
Self-gravitating condensates have been proposed as potential candidates for modelling dark matter. In this paper, we numerically investigate the dynamics of dark matter utilizing t…
