Based on the generalized model of the cubic-quintic Gross-Pitaevskii equation with polytropic approximation, we novelly utilize an F-expansion method to identify bright soliton dynamics of systems modelled by the cubic-quintic Gross-Pitaevskii with ...

Standing waves of the Anderson-Gross-Pitaevskii equation
In this paper, we study standing waves for the Anderson-Gross-Pitaevskii equation in dimension 1 and 2. The Anderson-Gross-Pitaevskii equation is a nonlinear Schrödinger equation with a confining potential and a multiplicative spatial white noise ...

Remarks on the Blow-Up Solutions for the Critical Gross-Pitaevskii Equation
This paper is concerned with the blow-up solutions of the critical Gross-Pitaevskii equation, which models the Bose-Einstein condensate. The existence and qualitative properties of the minimal blow-up solutions are obtained.

Comparison of finite‐difference schemes for the Gross‐Pitaevskii equation
A conservative finite‐difference scheme for numerical solution of the Gross‐Pitaevskii equation is proposed. The scheme preserves three invariants of the problem: the L 2 norm of the solution, the impulse functional, and the energy functional.

Polaron Dynamics in a Quasi-Two-Dimensional Bose–Einstein Condensate
The concept of polaron quasiparticles was first introduced in the pioneering papers by Landau and Feynman in the 1930s and 1940s. It describes the phenomenon of an external particle producing a bound state in an embedded medium.

Toward Coherent Polaritonic Devices Operating at Room Temperature
Polariton condensate formation and long‐range coherent transport is demonstrated using molecular exciton polaritons at room temperature (left). Waveguides and related photonic structures, such as Y‐splitters and interferometers, are realized via a focused ion beam etching of the planar microcavity. Coherent propagation of the condensate is demonstrated

Domain Walls in the Coupled Gross–Pitaevskii Equations [PDF]
A thorough study of domain wall solutions in coupled Gross-Pitaevskii equations on the real line is carried out including existence of these solutions; their spectral and nonlinear stability; their persistence and stability under a small localized potential. The proof of existence is variational and is presented in a general framework: we show that the
