Statistical Thermodynamics
1 Statistical ThermodynamicsProfessor Dmitry GaraninStatistical physicsMay 17, 2021I. PREFACES tatistical physics considers systems of a large number of entities (particles) such as atoms, molecules, spins, etc. Forthese system it is impossible and even does not make sense to study the full microscopic dynamics. The only relevantinformation is, say, how many atoms have a particular energy, then one can calculate the observable thermodynamicvalues. That is, one has to know the distribution function of the particles over energies that defines the macroscopicproperties. This gives the namestatistical physicsand defines the scope of this approach outlined above can be used both at and off equilibrium. The branch of physics studying non-equilibrium situations is calledphysical kinetics. In this course, we study only Statistical physics at equilibrium. Itturns out that at equilibrium the energy distribution function has an explicit general form and the only problem isto calculate the observables.
