Solitons for the cubic-quintic nonlinear Schrödinger equation with time and space modulated coefficients
(2009)
In this paper, we construct, by means of similarity transformations, explicit solutions to the cubic–quintic nonlinear Schrödinger equation with potentials and nonlinearities depending on both time and spatial coordinates. ...

Stationarity, ergodicity, and entropy in relativistic systems
(European Physical Society, 2009)
Recent molecular-dynamics simulations show that a dilute relativistic gas equilibrates to a Jüttner velocity distribution if ensemble velocities are measured simultaneously in the observer frame. The analysis of relativistic ...

Solitons in quasi-one-dimensional Bose-Einstein condensates with competing dipolar and local interactions
(2009)
We study families of one-dimensional matter-wave bright solitons supported by the competition of contact and dipole-dipole (DD) interactions of opposite signs. Soliton families are found, and their stability is investigated ...

Comparative depth-profiling analysis of nanometer-metal multilayers by ion-probing techniques
(ScienceDirect, 2009-04)
We examine here the depth resolution (interface width) in elemental analysis and depth profiling of complex layer systems of three ion-probing techniques, each of which has pros and cons: • Rutherford backscattering ...
