 Path integral Monte Carlo

Path integral Monte Carlo (PIMC) is a computational technique used to study quantum many-body systems at finite temperatures. It combines principles from quantum mechanics, statistical mechanics, and numerical simulation to provide insights into the behavior of systems of particles, such as atoms and molecules, where quantum effects are significant. ### Key Concepts of Path Integral Monte Carlo: 1. **Path Integrals**: PIMC is based on the Feynman path integral formulation of quantum mechanics.
