Project Structure

TimeEvolver                     TimeEvolver software package included as submodule
scripts                         bash scripts for running the programm for various parameter choices
CMakeLists.txt                  file needed for cmake
quantumBreaking.cpp             main function
quantumBreakingHamiltonians.*   defining the Hamiltonian of the system

External Requirements

Note that this project requires following external libraries

• Intel Math Kernel Library (MKL)
• BOOST
• HDF5

Compilation

mkdir build; cd build     # create and use a build directroy
cmake ..                  # configuration
cmake --build .           # compilation and linking (or type "make")

Important: the submodule TimeEvolver is not pulled automatically. If it's the first time you need to use --init first.

git submodule update --init --recursive

For problems during compilation, e.g. related to the version of BOOST, we refer to the repository of the TimeEvolver.
