Acoustic radiation from vortex-barrier interaction in atomic Bose-Einstein condensate
K. Suthar, Arko Roy, D. Angom
We examine the dynamics of a vortex dipole in the Bose-Einstein condensates (BECs) of trapped dilute atomic gases at zero temperature in the presence of a Gaussian barrier potentia…

Finite temperature dynamics of vortices in Bose-Einstein condensates
S. Gautam, Arko Roy, Subroto Mukerjee
We study the dynamics of a single and a pair of vortices in quasi two-dimensional Bose-Einstein condensates at finite temperatures. We use the stochastic Gross-Pitaevskii equation,…

Goldstone modes and bifurcations in phase-separated binary condensates at finite temperature
Arko Roy, S. Gautam, D. Angom
We show that the third Goldstone mode, which emerges in binary condensates at phase-separation, persists to higher inter-species interaction for density profiles where one componen…
