play-with-potentials

Python scripts for exploring and visualizing effective interaction potentials and comparing them with Lennard-Jones behavior.

Overview

This repository contains lightweight analysis scripts that compute attractive/repulsive potential terms and generate publication-style plots of (U(r)). It is intended for quick exploratory studies and figure generation.

Features

• Multiple script variants for potential analysis (plot_u_v0.py, plot_u_v1.py, plot_u.py).
• Comparison against Lennard-Jones reference curves.
• PDF figure export (u_of_r.pdf) using LaTeX-rendered labels in Matplotlib.

Requirements

• Python 3.10+
• numpy
• matplotlib
• A working LaTeX installation (for matplotlib.rcParams['text.usetex'] = True)

Installation

python3 -m venv .venv
source .venv/bin/activate
pip install numpy matplotlib

Usage

python3 plot_u.py

This writes u_of_r.pdf to the repository root.

Repository Contents

• plot_u.py: Two-panel visualization varying both (d) and (\rho).
• plot_u_v1.py: Single-panel sweep over (d).
• plot_u_v0.py: Baseline single-case plot.
• u_of_r.pdf: Example generated output.
