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.…
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…
Bio-Derived Graphite from Pterocarpus marsupium Leaves for rGO-MoO Nanocomposites with Enhanced Photocatalytic Efficiency
P. Princeya Mary, M. Kumaresavanji, P. Sundara Venkatesh +2
This study presents a sustainable approach to synthesize bio-graphite from Pterocarpus marsupium (Indian Kino) leaves without using chemical catalysts, activating agents, or organi…
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…
