A general variational approach for equilibrium phase boundaries of trapped spin-1 Bose-Einstein condensates
Sahil Satapathy, Projjwal K. Kanjilal, A. Bhattacharyay
We develop a simple and general variational method to estimate the solutions of the Gross-Pitaevskii equations and obtain the corresponding density profiles for all spin states of…
Multi-component states for trapped spin-1 Bose-Einstein Condensates in the presence of magnetic field
Projjwal K. Kanjilal, A. Bhattacharyay
In presence of a magnetic field, multi-component ground states appear in trapped spin-1 Bose-Einstein condensates for both ferromagnetic and anti-ferromagnetic types of spin-spin i…
A variational approach for the ground state profile of a trapped spinor-BEC: A detailed study of phase transition in spin-1 condensate at zero magnetic field
Projjwal K. Kanjilal, A. Bhattacharyay
In this article we introduce a multi-modal variational method to analytically estimate the full number- and corresponding energy-density profile of a spin-1 Bose-Einstein condensat…
Spin domains in ground state of a trapped spin-1 condensate: A general study under Thomas-Fermi approximation
Projjwal Kanti Kanjilal, Arijit Bhattacharyay
Investigation of ground state structures and phase separation under confinement is of great interest in spinor Bose Einstein Condensates (BEC). In this paper we show that, in gener…
Probing non-locality of interactions in a Bose-Einstein Condensate using solitons
Abhijit Pendse, A. Bhattacharyay
We consider a Bose-Einstein Condensate(BEC) with non-local inter-particle interactions. The local Gross-Pitaevskii(GP) equation is valid for the gas parameter $ν=: a^{3} n_{0} << 1…
Effect of non-local interactions on the vortex solution in Bose-Einstein Condensates
Abhijit Pendse, A. Bhattacharyay
We consider the Gross-Pitaevskii (GP) model of a Bose-Einstein Condensate (BEC) to study a single vortex line in the presence of non-local repulsive s-wave scattering. We show that…
