Collective excitations of two-dimensional Bose-Einstein Condensate in liquid phase with spin-orbit coupling
Saswata Sahu, Dwipesh Majumder
We have studied the collective excitation of Bose-Einstein condensate of short range weak interacting atoms with spin-orbit coupling (SOC) in two dimension in liquid phase. In our…
Collective spin density excitations of fractional quantum Hall states in dilute ultracold Bose atoms
Moumita Indra, Dwipesh Majumder
We have studied collective spin density excitations of fractional quantum Hall effect (FQHE) in rotating Bose-Einstein condensation for the three filling fractions of first series…
Study of partially polarized fractional quantum Hall states
Moumita Indra, Debashis Das, Dwipesh Majumder
We have studied the partially spin-polarized fractional quantum Hall states using Chern Simon's theory and plasma picture proposed by Halperin. Using these theoretical techniques w…
Roton minimum at filled fractional quantum Hall effect of Bose particles
Debashis Das, Saswata Sahu, Dwipesh Majumder
We have studied the collective excitation of fractional quantum Hall effect (FQHE) in the rotating Bose-Einstein condensate (BEC) using CF theory at the filling fraction . T…
Bose-Einstein Condensation in nonuniform rotation
Saswata Sahu, Dwipesh Majumder
In this work, we would like to present the Bose-Einstein Condensation in such a system where rotation is decreasing radially from the centre of the condensate. That non-uniform rot…
