# A simple [Ising model](https://en.wikipedia.org/wiki/Ising_model) simulator written in Rust

This project lets you simulate the d-dimensional Ising model in two modes:

- **mcmc**: Computes an approximation of the energy and magnetization distributions using an MCMC cluster algorithm as described in . In 2D, it also plots the resulting lattice.

- **exact** (small lattices only): Iterates over all possible states using a [Gray code](https://en.wikipedia.org/wiki/Gray_code) algorithm and plots the exact energy and magnetization distributions.

### Installation

* Download a prebuilt binary from the [releases](https://github.com/tchaumeny/RustIsing/releases) section.

* Or, build from sources using Cargo ([see documentation](https://doc.rust-lang.org/cargo/guide/working-on-an-existing-project.html)).

### Examples

##### 2500x2500 lattice at critical temperature

    ising --beta 0.4407 -n 2500 mcmc --iter 1000

##### Magnetization on a 10x10x10 lattice just below critical temperature

    ising -d 3 --beta 0.24 -n 10 mcmc -i 50000
