Introduction to Statistical Physics

Statistical physics is one of the fundamental branches of modern physics; through its probabilistic approach, it establishes relationships between the microscopic and the macroscopic. It deals with the behavior of systems containing a very large number of particles (atoms, molecules, photons, etc.) and links macroscopic quantities—such as pressure, temperature, etc.—that characterize their state of thermodynamic equilibrium to quantities that define the microscopic state of their constituents. This course unit, an introduction to statistical physics, will cover the microcanonical and canonical ensembles and establish the connection between the partition function and thermodynamic quantities such as average energy, pressure, temperature, and entropy. These results will be illustrated using ideal gases and a few simple quantum systems.
