After taking this module students should be able to:
describe such ideas as phase changes and chemical potential.
describe low temperature phenomena from a macroscopic and microscopic point of view.
explain the basic concepts of statistical mechanics and their application to investigate the properties of matter.
This module aims to:
a) build on the introductory thermodynamics course, introducing such ideas as phase changes and chemical potential.
b) introduce phenomena that occur at low temperatures, and to explain these from both a macroscopic and a microscopic point of view.
c) introduce the concepts of statistical mechanics, and use these in particular to investigate the properties of matter.
Reminder: Thermodynamic potentials, Maxwell relations, thermodynamic variables
First order phase changes: Gibbs function and Clausius-Clapeyron equation
Second and higher order phase changes
Ehrenfests classification, examples of different order
Adiabatic demagnetisation: attainment of very low temperatures
Chemical Potential and its applications to open systems
Third Law of thermodynamics: entropy near absolute zero
Negative temperatures and population inversion
Superfluidity: properties of liquid helium
Assembly of distinguishable particles: Boltzmann distribution, Partition function, link to thermodynamic quantities, examples
Assembly of indistinguishable particles (gases): Fermi-Dirac and Bose-Einstein distributions, Maxwell-Boltzmann distribution, examples
