Potts model Monte Carlo simulation

Simulation of the Potts model for a university course in Monte Carlo simulations

Install dependencies

You need need Python3 with Tkinter and PIP. On Ubuntu 18.04, you can get them by typing (with sudo rights):

apt install python3 python3-tk python3-pip python3-dev 

Create a virtual environment to install the packages dependencies and Poetry dependency manager:

python3 -m venv potts-venv
source potts-venv/bin/activate
pip install poetry

Then use Poetry to install the necessary Python dependencies (via virtualenv and pip):

poetry install

Run GUI of Potts simulation

With the virtual environment still activated (source potts-venv/bin/activate), call

python main.py

TODO

• Speed up metropolis algorithm

Further ideas

• Add changeable boundary conditions
• Make parameters (e. g. magnetization coefficient) changeable in GUI
• Add simulation mode to loop e. g. over different temperatures
• Add more statistics to the GUI, e. g. distribution of spin values
