A finite-element toolbox for the stationary Gross–Pitaevskii equation with rotation

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present a new numerical system using classical finite elements with mesh adaptivity for computing stationary solutions of the Gross–Pitaevskii equation. The programs are written as a toolbox for FreeFem++ (www.freefem.org), a free finite-element software available for all existing operating systems. This offers the advantage to hide all technical issues related to the implementation of the finite element method, allowing to easily code various numerical algorithms. Two robust and optimized... Title of program: GPFEM Catalogue Id: AFBD_v1_0 Nature of problem The software computes 2D or 3D stationary solutions of the Gross-Pitaevskii equation with rotation. The main application is the computation of different types of vortex states (Abrikosov vortex lattice, giant vortex) in rotating Bose Einstein condensates. The software can be easily modified to take into account different related physical models.
