Sinusoidal Excitations in Two Component Bose-Einstein Condensates
Priyam Das, T. Solomon Raju, Utpal Roy +1
The non-linear coupled Gross-Pitaevskii equation governing the dynamics of the two component Bose-Einstein condensate (TBEC) is shown to admit pure sinusoidal, propagating wave sol…

Loss of superfluidity in the Bose-Einstein condensate in an optical lattice with cubic and quintic nonlinearity
Priyam Das, Manan Vyas, Prasanta K Panigrahi
In a one-dimensional shallow optical lattice, in the presence of both cubic and quintic nonlinearity, a superfluid density wave is identified in a Bose-Einstein condensate. Interes…
