QuantumLiquids/PEPS is a library for efficiently simulation the finite-size PEPS for two-dimension quantum many-body problems. It is still under building.

• PESS
• Fermionic PEPS

Please note that the project requires the following dependencies to be installed in order to build and run successfully:

• C++17 Compiler
• CMake (version 3.12 or higher)
• Intel MKL or OpenBlas
• MPI
• Boost::serialization, Boost::mpi (version 1.74 or higher)
• QuantumLiquids/TensorToolkit
• QuantumLiquids/UltraDMRG
• GoogleTest (if testing is required)

Clone the repository into a desired directory and change into that location:

git clone https://github.com/QuantumLiquids/PEPS.git
cd UltraDMRG

Using CMake:

mkdir build && cd build
cmake ..
make -j4 && make install

You may want to specify CMAKE_CXX_COMPILER as your favorite C++ compiler, and CMAKE_INSTALL_PREFIX as your install directory when you're calling cmake
