PYED: Exact diagonalization for finite quantum systems
Copyright (C) 2017, H. U.R. Strand
The python module pyed implements exact diagonalization for finite fermionic many-body quantum systems, together with calculations of several response functions in imagianary time.
The many-body system is defined using pytriqs second-quantized operators and the response functions are stored in pytriqs Green's function containters.
The original purpose of pyed is to provide exact solutions to small finite systems, to be used as benchmarks and tests for stochastic many-body solvers.
Dependencies
pyed requires the triqs library to be installed from the unstable banch or version 1.5 scheduled for release late 2017.
Installation
To do: Add setup_utils install script
There is currently no formal installation scripts packed with pyed. To use and develop the module simply ammend your PYTHON_PATH with the ./pyed/ folder, e.g., add the follwing
export PYTHON_PATH=${HOME}/path/to/pyed:$PYTHON_PATH
in your .bashrc, .bash_profile, or .profile file.
