EDIkondo: an Exact Diagonalization algorithm for alkaline-earth atoms Kondo-like problems.

(This is a beta version softwware)

This is Lanczos-based diagonalization method for Kondo-like problems, exploiting distributed memory MPI parallelisation.

Dependencies

The code is written around the SciFortran library, using EDIpack2 as a template. Dependencies are:

• gfortran > 11.0.0 OR ifort > 13.0
• cmake > 3.5.0
• MPI
• SciFortran

Installation

Installation is available using CMake.

Clone the repo:

git clone https://github.com/edipack/EDIkondo

and from the just created directory make a standard out-of-source CMake compilation:

mkdir build
cd build
cmake ..
make
make install

The CMake compilation can be controlled using the following additional variables, default values between < >:

• -DPREFIX=prefix directory <~/opt/>
• -DUSE_MPI=<yes>/no
• -DVERBOSE=yes/<no>
• -DBUILD_TYPE=<RELEASE>/TESTING/DEBUG

System loading:

The library can be loaded into the operative system using one of the following, automatically generated, methods:

• environment module file ~/.modules.d/edikondo/<PLAT>
• homebrew bash script <PREFIX>/etc/config_edikondo.sh
• pkg-config file in ~/.pkg-config.d/edikondo.pc

Method 2. has the advantage of making unload operation feasible.

Uninstall

The library is removed with the command:

make uninstall

from the same building directory as for the installation part.
