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…
