Thomas Fermi approximation and large- quantum mechanics
Sukla Pal, Jayanta K. Bhattacharjee
We note that the Thomas Fermi limit of Gross Pitaevskii equation and limit of quantum mechanics, where is the dimensionality of space, are based on the same point of vie…
Gross Pitaevskii Equation with a Morse potential: bound states and evolution of wave packet
Sukla Pal, Jayanta K. Bhattacharjee
We consider systems governed by the Gross Pitaevskii equation (GPE) with the Morse potential as the trapping potential. For positive values of the coupl…
Wave packet dynamics for a non-linear Schrodinger equation: Qualitative changes with changes in the initial width
Sukla Pal, J. K. Bhattacharjee
The propagation of an initially Gaussian wave packet of width in a cubic non-linear Schrodinger equation with a negative coupling constant for the nonlinear term is considere…
Ground state of the one dimensional Gross-Pitaevskii equation with a Morse potential
Sukla Pal, Jayanta K. Bhattacharjee
We have studied the ground state of the Gross-Pitaevskii equation (nonlinear Schrodinger equation) for a Morse potential via a variational approach. It is seen that the ground stat…
Wave-packet dynamics for a coupled Gross-Pitaevskii equation
Sukla Pal, Jayanta K. Bhattacharjee
Starting from coupled Gross-Pitaevskii equation (GPE) describing the dynamics of binary Bose Einstein Condensate (BEC), we have explored the dynamics of the width of initial wave-p…
