Formation, dynamics and stability of coreless vortex dipoles in phase-separated binary condensates
S. Gautam, P. Muruganandam, D. Angom
We study the motion of the Gaussian obstacle potential created by blue detuned laser beam through a phase-separated binary condensate in pancake-shaped traps. For the velocity of t…
Annihilation of vortex dipoles in an Oblate Bose-Einstein Condensate
Shashi Prabhakar, R. P. Singh, S. Gautam +1
We theoretically explore the annihilation of vortex dipoles, generated when an obstacle moves through an oblate Bose-Einstein condensate, and examine the energetics of the annihila…
On Berezinskii-Kosterlitz-Thouless Phase Transition in Quasi-One Dimensional Bose-Einstein Condensate
Vivek M. Vyas, Sandeep Gautam, Prasanta K. Panigrahi
We show that quasi-one dimensional Bose-Einstein condensate under suitable conditions can exhibit a Berezinskii-Kosterlitz-Thouless phase transition. The role played by quantized v…
Coreless vortex dipoles and bubbles in phase-separated binary condensates
S. Gautam, P. Muruganandam, D. Angom
Vortex dipoles are generated when an obstacle moves through a superfluid. In case of phase-separated binary condensates, with appropriate interaction parameters in pan-cake shaped…
