Nonlinear Time-dependent Schrä Odinger Equations: the Gross-pitaevskii Equation with Double-well Potential
نویسنده
چکیده
We consider a class of SchrÄodinger equations with a symmetric double-well potential and an external, both repulsive and attractive, nonlinear perturbation. We show that, under certain conditions, the reduction of the time-dependent equation to a two-mode equation gives the dominant term of the solution with a precise estimate of the error.

Nonlinear modes for the Gross - Pitaevskii equation – demonstrative computation approach
A method for the study of steady-state nonlinear modes for Gross-Pitaevskii equation (GPE) is described. It is based on exact statement about coding of the steady-state solutions of GPE which vanish as x → +∞ by reals. This allows to fulfill demonstrative computation of nonlinear modes of GPE i.e. the computation which allows to guarantee that all nonlinear modes within a given range of paramet...
متن کاملBounds on the tight-binding approximation for the Gross–Pitaevskii equation with a periodic potential
We justify the validity of the discrete nonlinear Schrödinger equation for the tight-binding approximation in the context of the Gross–Pitaevskii equation with a periodic potential. Our construction of the periodic potential and the associated Wannier functions is based on the previous work [7], while our analysis involving energy estimates and Gronwall’s inequality addresses time-dependent loc...
متن کاملIntegrability of the Gross-Pitaevskii Equation with Feshbach Resonance management
In this paper we study the integrability of a class of Gross-Pitaevskii equations managed by Feshbach resonance in an expulsive parabolic external potential. By using WTC test, we find a condition under which the Gross-Pitaevskii equation is completely integrable. Under the present model, this integrability condition is completely consistent with that proposed by Serkin, Hasegawa, and Belyaeva ...
متن کاملGeometric Analysis of Bifurcation and Symmetry Breaking in a Gross–Pitaevskii Equation
Gross–Pitaevskii and nonlinear Hartree equations are equations of nonlinear Schrödinger type that play an important role in the theory of Bose–Einstein condensation. Recent results of Aschbacher et al. (3) demonstrate, for a class of 3-dimensional models, that for large boson number (squared L norm), N, the ground state does not have the symmetry properties of the ground state at small N. We pr...
متن کاملA Local Strong form Meshless Method for Solving 2D time-Dependent Schrödinger Equations
This paper deals with the numerical solutions of the 2D time dependent Schr¨odinger equations by using a local strong form meshless method. The time variable is discretized by a finite difference scheme. Then, in the resultant elliptic type PDEs, special variable is discretized with a local radial basis function (RBF) methods for which the PDE operator is also imposed in the local matrices. Des...
