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…
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…
Dynamic instabilities and turbulence of merged rotating Bose-Einstein condensates
Anirudh Sivakumar, Pankaj Kumar Mishra, Ahmad A. Hujeirat +1
We present the simulation results of merging harmonically confined rotating Bose-Einstein condensates in two dimensions. Merging of the condensate is triggered by positioning the r…
