We present new version of previously published Fortran and C programs for solving the
Gross–Pitaevskii equation for a Bose–Einstein condensate with contact interaction in one …

Abstract We present Open Multi-Processing (OpenMP) version of Fortran 90 programs for
solving the Gross–Pitaevskii (GP) equation for a Bose–Einstein condensate in one, two, and …

Motivated by recent experiments, we investigate a single 133 Cs impurity in the center of a
trapped 87 Rb Bose-Einstein condensate (BEC). Within a zero-temperature mean-field …

We investigate a quasi one-dimensional ${{}^{87}}\text {Rb} $ Bose–Einstein condensate in
a harmonic trap with an additional dimple trap (dT) in the center. Within a zero-temperature …

The scattering of a Bose-Einstein Condensate (BEC) from a Gaussian well and Gaussian
barrier is investigated over a wide range of depths and heights, respectively. We compare …

We numerically study the impact of Gaussian barrier height and width on gray solitons
population in a symmetric and asymmetric potential trap. The gray solitons are created in a …

We present an application of the Lagrangian variational method (LVM) to study the small-
oscillation dynamics and ground-state properties of an interacting Bose gas in a one …

We investigate the properties of a distinguishable single excited state impurity pinned in the
center of a trapped Bose–Einstein condensate in a one-dimensional harmonic trapping …

The postulates of the eigenstate thermalization hypothesis (ETH) expresses that the
thermalization occurs due to the individual eigenstate of the system's Hamiltonian. But the …

We study the quantum dynamics of the two impurities in a trapped quasi-one-dimensional
Bose–Einstein condensate (BEC). We explore the effect of impurity-BEC and impurity …
