Numerical solution of Multiconfigurational Time Dependent Hartree method for Bosons(MCTDHB) in one dimension.

MCTDHB in 1-dimension

A package for numerical time evolution of multiconfigurational time-dependent Hartree method for bosons(MCTDHB). This method is a generalization of the mean field approach, where the atoms have more than one single particle state for occupation and all the possible configurations of particles in these single particle states (a.k.a orbitals) are consided. For a first contact with the analytical derivation of the method see:

• Phys. Rev. A, 77, 033613 (2008)
• Phys. Reports, 324 (2000)
• ultracold.org documentation

Dependencies

To properly install the package, the following dependencies are required

• cmake --version >= 16
• intel oneAPI at least the MKL library and the classic C/C++ compiler
• data input/output library
• differential equation library

after the installation of these dependencies, copy the include files of the cpy-dataio and odelib to the directory ${HOME}/.local/include and the libraries to ${HOME}/.local/lib (create these dirs if needed).

Installation

If all dependencies are satisfied, it is easy to install with cmake. Inside the directory cloned just run

cmake -S . -B build -DCMAKE_C_COMPILER=icc && cmake --build build --target install

The library will be located at lib dir and the main executable at bin.

Basic usage - main program (in development)
