Adaptation and assessement of Projected Nesterov accelerated gradient flow to compute stationary states of nonlinear Schrödinger equations

Résumé

The aim of the paper is to derive minimization algorithms based on the Nesterov accelerated gradient flow [23, 24, 25] to compute the ground state of nonlinear Schrödinger equations, which can potentially include a fractional laplacian term. A comparison is developed with standard gradient flow formulations showing that the Nesterov accelerated gradient flow has some interesting properties but at the same time finds also some limitations due to the nature of the problem. A few simulations are finally reported to understand the behavior of the algorithms and open the path to further complicate questions that require more advanced studies concerning the application of the Nesterov accelerated gradient flow to nonlinear Schrödinger equations.
