Description
Statistical physics is one of the fundamental branches of modern physics which, through its probabilistic approach, establishes relations between the microscopic and the macroscopic. It deals with the evolution of systems with a very large number of particles (atoms, molecules, photons, etc.) and links macroscopic quantities such as pressure, temperature, etc. characterizing their state at thermodynamic equilibrium to quantities defining the microscopic state of their constituents. This introductory course in statistical physics will deal with the microcanonical and canonical sets, and will make the link between the partition function and thermodynamic quantities such as average energy, pressure, temperature and entropy. These results will be illustrated on perfect gases and on some simple quantum systems.
