Manuscript Title: A Simple Quantum Integro-Differential Solver (SQuIDS) | ||

Authors: Carlos A. Argüelles Delgado, Jordi Salvado, Christopher N. Weaver | ||

Program title: SQuIDS | ||

Catalogue identifier: AEXG_v1_0Distribution format: tar.gz | ||

Journal reference: Comput. Phys. Commun. 196(2015)569 | ||

Programming language: C++11. | ||

Computer: 32- and 64-bit x86. | ||

Operating system: Linux, Mac OS X, FreeBSD. | ||

RAM: Proportional to the number of nodes, the dimension of the Hilbert space, the number of scalar functions, and the number of density matrixes used in the problem. | ||

Keywords: Quantum mechanics, Ordinary differential equations, SU groups. | ||

PACS: 03.65.-wp, 02.30.Hq, 11.30.Hv, 11.30.Ly. | ||

Classification: 11.1. | ||

External routines: GNU Scientific Library (http://www.gnu.org/software/gsl/). | ||

Nature of problem:Solve the evolution of open quantum systems of Hilbert space dimension N with self interactions and interaction with classical fields. | ||

Solution method:The SU(N) algebra is implemented as a C++ object and is embedded into the GSL ordinary differential equation solver. | ||

Restrictions:The code is only implemented up to Hilbert spaces of dimension six, but a Mathematica notebook is provided in order to generate higher dimensional solutions. Furthermore, only ordinary differential equation solution methods that require only the first derivative can be used. | ||

Running time:Proportional to the number of nodes, the dimension of the Hilbert space, the number of scalar functions, the number of density matrixes, and the numerical precision used in the problem. |
