Effective approximation for a nonlocal stochastic Schrödinger equation with oscillating potential

نویسندگان

چکیده

We study the effective approximation for a nonlocal stochastic Schrödinger equation with rapidly oscillating, periodically time-dependent potential. use natural diffusive scaling of heterogeneous system and limit behavior as parameter tends to 0. This is motivated by data assimilation non-Gaussian uncertainties. The operator in this partial differential generator Lévy-type process (i.e., class anomalous diffusion processes), non-integrable jump kernel. With help two-scale convergence technique, we establish equation. More precisely, show that has it approximates original weakly Sobolev-type space strongly $$L^2$$ space. In particular, holds when fractional Laplacian.

Integrable nonlocal nonlinear Schrödinger equation.

A new integrable nonlocal nonlinear Schrödinger equation is introduced. It possesses a Lax pair and an infinite number of conservation laws and is PT symmetric. The inverse scattering transform and scattering data with suitable symmetries are discussed. A method to find pure soliton solutions is given. An explicit breathing one soliton solution is found. Key properties are discussed and contras...

Chaoticons described by nonlocal nonlinear Schrödinger equation

It is shown that the unstable evolutions of the Hermite-Gauss-type stationary solutions for the nonlocal nonlinear Schrödinger equation with the exponential-decay response function can evolve into chaotic states. This new kind of entities are referred to as chaoticons because they exhibit not only chaotic properties (with positive Lyapunov exponents and spatial decoherence) but also soliton-lik...

Schrödinger operators with oscillating potentials ∗

Schrödinger operators H with oscillating potentials such as cos x are considered. Such potentials are not relatively compact with respect to the free Hamiltonian. But we show that they do not change the essential spectrum. Moreover we derive upper bounds for negative eigenvalue sums of H.

Blowup Analysis for a Nonlocal Reaction Diffusion Equation with Potential

In this paper we investigate a nonlocal reaction diffusion equation with potential, under Neumann boundary. We obtain the complete classification of the parameters for which the solution blows up in finite time or exists globally. Moreover, we study the blowup rate and the blowup set for the blowup solution. Key–Words: Nonlocal diffusion, Blow up, Blowup rate, Blowup set

Effective noise theory for the nonlinear Schrödinger equation with disorder.

For the nonlinear Shrödinger equation with disorder it was found numerically that in some regime of the parameters Anderson localization is destroyed and subdiffusion takes place for a long time interval. It was argued that the nonlinear term acts as random noise. In the present work, the properties of this effective noise are studied numerically. Some assumptions made in earlier work were veri...
