QuantumClusterTheories

Julia package for the quantum cluster theories in condensed matter physics, including cluster perturbation theory (CPT), variational cluster approach (VCA), etc.

Introduction

Based on the symbolic operator representation of a quantum lattice system in condensed matter physics that is generated by the package QuantumLattices, the quantum cluster theories in condensed matter physics, including cluster perturbation theory (CPT), variational cluster approach (VCA), etc, are implemented for fermionic, hard-core-bosonic and spin systems.

Installation

In Julia v1.10+, please type ] in the REPL to use the package mode, then type this command:

pkg> add QuantumClusterTheories

Getting Started

Examples of quantum cluster theories for quantum lattice system

Note

Due to the fast development of this package, releases with different minor version numbers are not guaranteed to be compatible with previous ones before the release of v1.0.0. Comments are welcomed in the issues.

Python counterpart

HamiltonianPy: in fact, the authors of this Julia package worked on the python package at first and only turned to Julia later.
