Quantum phases and spectrum of collective modes in a spin-1 BEC with spin-orbital-angular-momentum coupling
Paramjeet Banger, Rajat, Arko Roy +1
Motivated by the recent experiments [Chen et al., Phys. Rev. Lett 121, 113204 (2018), Chen et al., Phys. Rev. Lett. 121, 250401 (2018)], we investigate the low-lying excitation spe…
Oscillating Solitons and AC Josephson Effect in Ferromagnetic Bose-Bose Mixtures
Sebastiano Bresolin, Arko Roy, Gabriele Ferrari +2
Close to the demixing transition, the degree of freedom associated to relative density fluctuations of a two-component Bose-Einstein condensate is described by a non-dissipative La…
Non-linear response of interacting bosons in a quasiperiodic potential
Debamalya Dutta, Arko Roy, Kush Saha
We theoretically study the electric pulse-driven non-linear response of interacting bosons loaded in an optical lattice in the presence of an incommensurate superlattice potential.…
Collective excitations in cigar-shaped spin-orbit coupled spin-1 Bose-Einstein condensates
Rajat, Arko Roy, Sandeep Gautam
We theoretically study the collective excitations of a spin-orbit-coupled spin-1 Bose-Einstein condensate with antiferromagnetic spin-exchange interactions in a cigar-shaped trappi…
Effective potentials in a rotating spin-orbit-coupled spin-1 spinor condensate
Paramjeet Banger, R. Kishor Kumar, A. Roy +1
We theoretically study the stationary-state vortex lattice configurations of rotating spin-orbit- and coherently-coupled spin-1 Bose-Einstein condensates trapped in quasi-two-dimen…
FORTRESS II: FORTRAN programs for solving coupled Gross-Pitaevskii equations for spin-orbit coupled spin-2 Bose-Einstein condensate
Paramjeet Banger, Pardeep Kaur, Arko Roy +1
We provide here a set of three OpenMP parallelized FORTRAN 90/95 programs to compute the ground states and the dynamics of trapped spin-2 Bose-Einstein condensates (BECs) with anis…
