## Course description

## Objectives and Content

**Objectives:**

The course is an extension of the corresponding topics in PHYS113 and the objective is to give the students a thorough understanding of the theory and methods of statistical physics and thermodynamics.

**Content:**

The course covers the Gibbs ensemble formulation of statistical thermodynamics, both in classical and quantum formalism: applications for gases, chemical reactions, binary molecular systems, magnetization, electron gas and photon gas. The thermodynamics of mixtures and multi-phase systems will be discussed, along with examples of phase transitions and phase diagrams. Examples will be given on the use of statistical physics to describe the macroscopic properties of a system with a large number of particles from the microscopic properties of the particles that the system consists of. Statistical physics is widely applied e.g. in astrophysics, condensed matter physics, and fluid theory.

## Learning Outcomes

On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

**Knowledge**

The student

- Has thorough knowledge on different classical and quantum mechanical distribution functions
- Can explain the procedures for deriving the relation between thermodynamic parameters such as pressure, temperature, entropy and heat capacity from the distribution functions.
- Can explain phase transitions and magnetization in magnetic systems

**Skills**

The student

- Can apply the theory on different types of gasses: ideal classic, diatomic, quantum Fermi gasses such as quarks, electrons or baryons, quantum Bose gases such as photons, gluons or mesons.
- Can analyze phase diagrams, phase transitions and explain the concept of latent heat

**General competence**

The student

- Can apply the methods of statistical physics in other fields of physics and related fields.
