Special solutions of the Riccati equation with applications to the Gross-Pitaevskii nonlinear PDE

open access: yesElectronic Journal of Differential Equations, 2010
A method for finding solutions of the Riccati differential equation $y' = P(x) + Q(x)y + R(x)y^2$ is introduced. Provided that certain relations exist between the coefficient $P(x)$, $Q(x)$ and $R(x)$, the above equation can be solved in closed form.

The Cauchy problem for the Gross–Pitaevskii equation

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2006
We prove global wellposedness of the two-dimensional and three-dimensional Gross–Pitaevskii equations in the natural energy space. Résumé On établit que le problème de Cauchy pour l'équation de Gross–Pitaevskii est bien posé dans l'espace d'énergie naturel, en dimensions deux et trois.

Transverse Evolution Operator for the Gross-Pitaevskii Equation in Semiclassical Approximation

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2005
The Gross-Pitaevskii equation with a local cubic nonlinearity that describes a many-dimensional system in an external field is considered in the framework of the complex WKB-Maslov method.

Density matrix form of Gross-Pitaevskii equation

open access: yes, 2014
We consider the generalized pure state density matrix which depends on different time moments. The evolution equation for this density matrix is obtained in case where the density matrix corresponds to the solutions of Gross-Pitaevskii equation.

The Partition Function of the Bose-Einstein Condensation in Parabolic Trap

open access: yesMakara Seri Sains, 2012
We have discussed the partition function of the Bose-Einstein condensation in parabolic trap associated to the one-dimensional Gross-Pitaevskii equation. The partition function itself is constructed by considering all the energy levels of the macroscopic
