### Description

This course has several objectives: [A] learn how to calculate the properties of a gas from its microscopic description in the context of kinetic theory, [B] understand the formalism of the different ensembles of statistical physics, [C] learn how to manipulate these ensembles to describe the macroscopic properties of perfect and real gases, liquids and solids, [D] understand the importance of the indiscernibility of particles and master the quantum statistical framework, and lastly [E] understand the emergence of important quantum effects in fermion, boson and photon gases.

It is based on the following plan:

- Chap I:
**Introduction**(from micro to macro, N-body problem, historical benchmarks) - Chap II:
**Kinetic theory of gases.**Distribution; Initial microscopic approach (temperature, pressure, effusion, transport coefficients) - Chap III:
**Classical statistics.**Perfect gases; paramagnetism; frozen systems; adsorption (Langmuir; Brunauer, Emmett & Teller); solids (Einstein, Debye) - Chap IV:
**Real gases.**Viriel; phase transitions (critical opalescence, phase coexistence, spinodal, critical point) - Chap V:
**Quantum statistics**Derivation of Bose-Einstein and Fermi-Dirac distributions; fermion gases (conduction electrons in metal, helium-3, white dwarfs, photoelectric effect); boson gases (Bose-Einstein condensation, thermodynamics between phases, helium-4 - fountain effect); photon gases (microscopic black-body theory, Planck's law, absorption and emission, thermodynamics of radiation (greenhouse effect, fossil radiation))

### Recommended prerequisite

It is highly recommended for students to have followed a Statistical Physics module in the Physics bachelor (L3) course.
