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 triqs second-quantized operators and the response functions are stored in triqs 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.

Installation

To install pyed using the python setuptools run

python setup.py install
