Bifurcations, stability, and mode evolution in segregated condensate mixtures
Sukla Pal, Arko Roy, D. Angom
We present new features of low energy Bogoliubov quasiparticle excitations of a two component Bose-Einstein condensate (TBEC) in quasi-2D geometry at zero temperature using Hartree…
Finite temperature expansion dynamics of Bose-Einstein condensates
Arko Roy, D. Angom
We explore the effects of finite temperature on the dynamics of Bose-Einstein condensates (BECs) after it is released from the confining potential. In addition, we examine the vari…
Characteristic temperature for the immiscible-miscible transition of binary condensates in optical lattices
K. Suthar, D. Angom
We study a two-species Bose-Einstein condensates confined in quasi-two-dimensional (quasi-2D) optical lattices at finite temperatures, employing the Hartree-Fock-Bogoliubov theory…
Ramifications of topology and thermal fluctuations in quasi-2D condensates
Arko Roy, D. Angom
We explore the topological transformation of quasi-2D Bose-Einstein condensates of dilute atomic gases, and changes in the low-energy quasiparticles associated with the geometry of…
Optical lattice influenced geometry of quasi-2D binary condensates and quasiparticle spectra
K. Suthar, D. Angom
We explore the collective excitations of optical lattices filled with two-species Bose-Einstein condensates (TBECs). We use a set of coupled discrete nonlinear Schrödinger equation…
