  • Roy, Arko; Gautam, S.; Angom, D. (Springer, 2015-04)
    We show that the third Goldstone mode in the two-species condensate mixtures, which emerges at phase-separation, gets hardened when the confining potentials have separated trap centers. The sandwich type condensate density ...
  • Gautam, S.; Roy, Arko; Mukerjee, Subroto (American Physical Society, 2014-01)
    We study the dynamics of a single vortex and a pair of vortices in quasi two-dimensional Bose-Einstein condensates at finite temperatures. To this end, we use the stochastic Gross–Pitaevskii equation, which is the Langevin ...
  • Roy, Arko; Gautam, S.; Angom, D. (American Physical Society, 2014-01)
    We show that the third Goldstone mode, which emerges in binary condensates at phase separation, persists to higher interspecies interaction for density profiles where one component is surrounded on both sides by the other ...
