A Spectral Analysis of the Nonlinear Schroedinger Equation in the Co-Exploding Frame

Autor: Chapman, SJ, Kavousanakis, M, Charalampidis, EG, Kevrekidis, IG, Kevrekidis, PG

The nonlinear Schrödinger model is a prototypical dispersive wave equation that features finite time blowup, either for supercritical exponents (for fixed dimension) or for supercritical dimensions (for fixed nonlinearity exponent). Upon identifying

A versatile algorithm for computing invariant manifolds

Autor: Broer, H. W., Hagen, A., Vegter, G., Gorban, AN, Kazantzis, NK, Kevrekidis, IG, Ottinger, HC, Theodoropoulos, C

Publikováno v: Model Reduction and Coarse-Graining Approaches for Multiscale Phenomena, 17-38
STARTPAGE=17;ENDPAGE=38;TITLE=Model Reduction and Coarse-Graining Approaches for Multiscale Phenomena

This paper deals with the numerical computation of invariant manifolds using a method of discretizing global manifolds. It provides a geometrically natural algorithm that converges regardless of the restricted dynamics. Common examples of such manifo

A Parrinello-Rahman approach to vortex lattices

Autor: Carretero-Gonzalez, R Kevrekidis, PG Kevrekidis, IG and Maroudas, D Frantzeskakis, DJ

We present a framework for studying vortex lattice patterns and their structural transitions, using the Parrinello-Rahman (PR) method for molecular-dynamics (MD) simulations. Assuming an interaction between vortices derived from a Ginzburg-Landau fie

Dark-in-bright solitons in Bose-Einstein condensates with attractive interactions

Autor: Kevrekidis, PG Frantzeskakis, DJ Malomed, BA Bishop, AR and Kevrekidis, IG

We demonstrate a possibility to generate localized states in effectively one-dimensional Bose-Einstein condensates with a negative scattering length in the form of a dark soliton in the presence of an optical lattice (OL) and/or a parabolic magnetic

Heterogeneous versus discrete mapping problem

Autor: Panos Kevrekidis, Kevrekidis Ig

Publikováno v: Physical review. E, Statistical, nonlinear, and soft matter physics. 64(5 Pt 2)

We propose a method for mapping a spatially discrete problem, stemming from the spatial discretization of a parabolic or hyperbolic partial differential equation of gradient type, to a heterogeneous one with certain comparable dynamical features pert
