Evolution of Goldstone mode in binary condensate mixtures
Arko Roy, S. Gautam, D. Angom
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 cen…

Fluctuation driven topological transition of binary condensates in optical lattices
K. Suthar, Arko Roy, D. Angom
We show the emergence of a third Goldstone mode in binary condensates at the phase-separation in quasi-1D optical lattices. We develop the coupled discrete nonlinear Schrödinger eq…

Fluctuation and interaction induced instability of dark solitons in single and binary condensates
Arko Roy, D. Angom
We show that the presence of soliton in a single-species condensate, at zero temperature, enhances the quantum depletion sufficient enough to induce dynamical instability of the sy…
