Geometry-induced modification of fluctuation spectrum in quasi-two-dimensional condensates
Arko Roy, D. Angom
We report the structural transformation of the low-lying spectral modes, especially the Kohn mode, from radial to circular topology as harmonic confining potential is modified to a…

Thermal suppression of phase separation in condensate mixtures
Arko Roy, D. Angom
We examine the role of thermal fluctuations in binary condensate mixtures of dilute atomic gases. In particular, we use Hartree-Fock-Bogoliubov with Popov approximation to probe th…

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…
