WavePacket (C++/Python)
Time-dependent simulation of open and closed quantum systems
Note: This package has been superseded by a Python-only package. See https://github.com/ulflor/wavepacket for the follow-up project. WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry. ... -

SoAx
Structure of Arrays of multiple types
...By means of C++(11) meta-template programming SoAx achieves maximal performance (efficient use of vector units and cache of modern CPUs) while providing a very convenient user interface (including object-oriented element handling) and flexibility. It has been designed to handle list-like sets of particles (similar to struct {int id; double[3] pos; float[3] vel;};) in the context of high-performance numerical simulations. It can be applied to many other problems. Please check the sample file main.cpp to see examples of code that you can write with SoAx. -

RAtom
solves nonlinear Kohn-Sham equation for the neutral atom.
RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from... -

WavePacket
Dynamics of quantum systems, controlled by external fields
WavePacket is a toolkit for numerical simulation of distinguishable particles. It can solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, as well as classical or quantum-classical Liouville equations. External electric fields can be added within the semiclassical dipole approximation, thus WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. ... -

Runge
Runge is an Interactive Solver for Systems of Differential Equations
...It uses Runge Rule to adjust step length to satisfy required precision on each step. It's effective. When it needs to compute derivatives (Jacobian matrix, for example) it does that analytically, i.e. without using numerical methods. It's portable. It works on Windows and Linux 32 and 64 bit and Mac OS X 64 bit. It's open. It allows you to implement and embed your own algorithms (aka "solvers"). It's easy to use. It allows to export results to MS Excel and MATLAB. It's multilingual. It currently supports Englis and Russian languages. ... -

LIME
LIME is a software tool for creating multiphysics simulation codes.
The Lightweight Integrating Multiphysics Environment for coupling codes (LIME) is a small software package for creating multiphysics simulation codes. LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve di fferent parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defi ned approach (with example templates), and interface requirements to enable the... -
