Interacting bosons in two-dimensional lattices with localized dissipation
Arko Roy, Kush Saha
Motivated by the recent experiment [Takafumi Tomita \emph{et al.}, Sci. Adv. {\bf 3}, (2017)], we study the dynamics of interacting bosons in a two-dimensional optical lattice with…

Splitting of singly and doubly quantized composite vortices in two-component Bose-Einstein condensates
Pekko Kuopanportti, Soumik Bandyopadhyay, Arko Roy +1
We study numerically the dynamical instabilities and splitting of singly and doubly quantized composite vortices in two-component Bose-Einstein condensates harmonically confined to…

FACt: FORTRAN toolbox for calculating fluctuations in atomic condensates
Arko Roy, Sukla Pal, S. Gautam +2
We develop a FORTRAN code to compute fluctuations in atomic condensates (FACt) by solving the Bogoliubov-de Gennes (BdG) equations for two component Bose-Einstein condensate (TBEC)…
