چکیده

Abstract We study the generalized hydrodynamics of one-dimensional classical non linear Schrӧdinger equation in attractive phase. thereby show that thermodynamic limit is entirely captured by solitonic modes and radiation absent. Our results are derived considering semiclassical quantum Bose gas, where Planck constant has a key role as regulator soliton gas. use our result to adiabatic interaction changes from repulsive phase, observing production obtaining exact analytical which excellent agreement with Monte Carlo simulations.

The smoothed particle hydrodynamics method for solving generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system

A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...

Exact Controllability of a Non-linear Generalized Damped Wave Equation: Application to the Sine-gordon Equation

In this paper, we give a sufficient conditions for the exact controllability of the non-linear generalized damped wave equation ẅ + ηẇ + γAw = u(t) + f(t, w, u(t)), on a Hilbert space. The distributed control u ∈ L2 and the operator A is positive definite self-adjoint unbounded with compact resolvent. The nonlinear term f is a continuous function on t and globally Lipschitz in the other variabl...

Differential Transform Method to two-dimensional non-linear wave equation

In this paper, an analytic solution is presented using differential transform method (DTM) for a class of wave equation. The emphasis is on the nonlinear two-dimensional wave equation. The procedures introduced in this paper are in recursive forms which can be used to obtain the closed form of the solutions, if they are required. The method is tested on various examples, and the results reveal ...
