# MeanFieldToolkit

[![Build Status](https://github.com/Anjishnubose/MeanFieldToolkit.jl/actions/workflows/CI.yml/badge.svg?branch=main)](https://github.com/Anjishnubose/MeanFieldToolkit.jl/actions/workflows/CI.yml?query=branch%3Amain)

MeanFieldToolkit.jl is a Julia package meant for solving generalized self-consistent mean-field equations on a lattice.

Currently supported :

* Lattice implementation is done through [TightBindingToolkit.jl](https://github.com/Anjishnubose/TightBindingToolkit.jl). Any custom lattice in d=1,2,3 is supported.

* User can input any two-site interaction in the form of arrays, and their corresponding mean-field equations. Simple four-fermion interactions are already built in (such as Hubbard, Spin-Spin interactions etc.).

* Can track any hopping and pairing order parameters.

* Self-consistentcy solver is implemented using [FixedPointToolkit.jl](https://github.com/Anjishnubose/FixedPointToolkit.jl). Can customize the solver, the tolerance of convergence, the maximum number of iterations and so on.

* Can checkpoint and save results into JLD2 files, and resume iterations from reading such files.

* Can plot results of order parameters, and the mean-field ground state energy as a function of iterations.
