  • Roy, Arko; Gautam, S.; Angom, D. (Cornell University Library, 2015-01)
    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 {\em sandwich} type condensate ...
  • Gautam, S.; Roy, Arko; Mukerjee, Subroto (Cornell University Library, 2013-10)
    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, which is the Langevin equation for the ...
  • Roy, Arko; Gautam, S.; Angom, D. (American Physical Society, 2013-01)
    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 component is surrounded on both sides by the other ...
