### Statistical Physics III University of Tsukuba

#### Course Overview

Following "Statistical Physics I, II", the fundamental principles and various statistical ensembles in Statistical Mechanics are applied to some important phenomena encountered in physics, namely phase transition and Landau phenomenological theory, semiconductor statistics, and quasi-Fermi potentials. A brief introduction to nonequilibrium statistical mechanics, namely, kinetic theory of ideal gas, linear response, and Boltzmann transport theory, is also explained.

#### Learning Achievement

1. The students are able to calculate thermodynamic properties of materials by the canonical ensembles.

2. The students are able to derive quantum statistics from the grand-caconical ensembles and to understand the classical limit.

3. The students are able to derive the formulas of the density of states and the spectrum of black-body radiation.

4. The students are able to calculate electric conductivity in metals.

#### Competence
