OpenMP Fortran programs for rotating dipolar Bose-Einstein condensates
Denis Mujo, Dušan Vudragović, Paulsamy Muruganandam +1
In this paper we present Open Multi-Processing (OpenMP) Fortran 90/95 programs to solve the Gross-Pitaevskii equation for a rotating dipolar Bose-Einstein condensate (BEC) in two a…
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…
A robust method to identify chimera states
S. Nirmala Jenifer, Riccardo Muolo, Paulsamy Muruganandam +1
Chimera states are one of the most intriguing phenomena in nonlinear dynamics, characterized by the coexistence of coherent and incoherent behavior in systems of coupled identical…
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…
