Comment:
Samlæses med FY811 og 2.del af FY509

Prerequisites:
None

Academic preconditions:
FY521 Introductory Quantum Mechanics I or KE524 Quantum Chemistry must have been attended.

Course introduction
The course gives an introduction to the fundamental concepts of thermodynamics and statistical mechanics and shows their applications to selected physical and chemical systems and to the interpretation of experiments.

Expected learning outcome
At the end of the course, the students should be able to:

1. Explain and apply the statistical basis of the laws of thermodynamics

2. Apply the relationships betwen thermal response functions and statistical correlations

3. Formulate and use equilibrium conditions in statistical mechanics

4. Apply the most common ensembles for calculations of average and dispersion values of standard variables

5. Calculate thermodynamics functions for classical and quantum gases

6. Write down partition sums for molecules and solids and calculate the appropriate thermodynamic variables

7. Apply the mean field approximation for strongly interacting systems

Subject overview
The topics are:

• Applications of statistical mechanics to simple, realistic systems, e.g. quantum systems, phase and chemical equilibria, and the mean field theory of interacting systems.
• Experimental exercises illustrate the importance of Fermi-Dirac statistics for the description of the properties of solids. A written report is written by groups of 1 or 2 students. The report must contain: the needed theory, the measured data, and an interpretation of the data.
• Vibration and rotation spectra for diatomic molecules.
• Einstein’s and Debye’s theories of lattice vibrations
• Black body radiation and Bose-Einstein condensation
• Phase changes are discussed on a statistical mechanical basis.
• Mean field theory of interacting systems: Ising model of ferro-magnetism and Debye-Hückel theory of diluted ionic solutions.
