Overview

opendf - a code to evaluate dual fermion (DF) diagrams to solve strongly correlated lattice problems on the lattice (a.k.a. Hubbard model at finite dimensions). It works with a conjuction with DMFT or any other method that produces input for DF calculations : local Green's functions, hybridization functions and vertex functions.

An example of input data is provided with unhybridized atomic limic data, generated by `tools/generate_atomic.cpp'.

Installation

The installation is a standard cmake-based procedure. To compile (on POSIX os):

• make some temporary directory, change to that directory and run : cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=${PATH_TO_INSTALL_LOCATION} ${PATH_TO_CODE}.
• customize cmake options, if some dependencies are not found (see description below or run ccmake for experts). By default testing is enabled: it can be disabled with -DTesting=OFF.
• make
• make test (optional)
• make install

Dependencies:

• c++11 - compatible c++ compiler
• cmake
• eigen3 (header-only) : http://eigen.tuxfamily.org/. CMake option: -DEIGEN3_INCLUDE_DIR=path_to_eigen3_headers.
• fftw. Cmake option : -DFFTW_ROOT=path_to_fftw_prefix (that is before include or lib).
• gftools (header-only; https://github.com/aeantipov/gftools; fetched automatically during build). Optionally can be fetched, installed and the location given by -DGFTOOLS_INCLUDE_DIR.
• ALPSCore : http://alpscore.org/. CMake option : -DALPS_ROOT=path_to_alpscore_prefix. The following alpscore dependencies are required:
  • Boost. Cmake option : -DBOOST_ROOT=path_to_boost_prefix.
  • MPI
  • HDF5 . Cmake option : -DHDF5_ROOT=path_to_hdf5_prefix.
  • gtest for testing
  • Doxygen (optional)

NB: Since c++11 support is required for the code to work, c++ dependencies (in particular, alpscore and boost) are required to be compiled in c++11 mode.
