ATUS-PRO: A FEM-based solver for the time-dependent and stationary Gross–Pitaevskii equation

Abstract ATUS-PRO is a solver-package written in C++ designed for the calculation of numerical solutions of the stationary- and the time dependent Gross–Pitaevskii equation for local two-particle contact interaction utilising finite element methods. These are implemented by means of the deal.II library (Bangerth et al., 0000) [1], (Bangerth et al., 2007) [2]. The code can be used in order to perform simulations of Bose–Einstein condensates in gravito-optical surface traps, isotropic and full anisotr... Title of program: ATUS-PRO Catalogue Id: AEZD_v1_0 Nature of problem Solving the Gross-Pitaevskii equation for Bose-Einstein condensates in external traps. Stationary solutions: computation of ground- as well as excited states. Real time propagation: calculation of time dependent solutions.
