Mode bifurcation in the Rayleigh-Taylor instability of binary condensates
Arko Roy, S. Gautam, D. Angom
We examine the generation and subsequent evolution of Rayleigh Taylor instability in anisotropic binary Bose-Einstein condensates. Considering a pancake-shaped geometry, to initiat…

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…

Position swapping and pinching in Bose-Fermi mixtures with two-color optical Feshbach resonances
S. Gautam, P. Muruganandam, D. Angom
We examine the density profiles of the quantum degenerate Bose-Fermi mixture of Yb-Yb, experimental observed recently, in the mean field regime. In this mixture the…
