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.

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.

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

Macroscopic quantum tunnelling of a Bose-Einstein condensate in a Cubic-Plus-Quadratic Well

open access: yesAAPPS Bulletin
We study the macroscopic quantum tunnelling of an interacting Bose-Einstein condensate in a cubic-plus-quadratic well that was approximately realized in recent experiment.

Stability analysis of 3D cubic-quintic Gross–Pitaevskii equation with elastic and inelastic collisions

open access: yesAIP Advances
In this paper, we study the stability of three-dimensional Bose–Einstein condensates of finite temperatures at which both elastic and inelastic collisions are taken into account.

Global solutions for 3D nonlocal Gross-Pitaevskii equations with rough data

open access: yesElectronic Journal of Differential Equations, 2012
We study the Cauchy problem for the Gross-Pitaevskii equation with a nonlocal interaction potential of Hartree type in three space dimensions. If the potential is even and positive definite or a positive function and its Fourier transform decays ...
