# **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](https://github.com/TRIQS/triqs).

## Installation

To install `pyed` using the python setuptools run

```

python setup.py install

```
