## Module content and teaching

###### Principal aims

The module will illustrate the important concepts of modern statistical physics using simple examples. It should give an appreciation of the fundamental role played by fluctuations in nature.

###### Principal learning outcomes

At the end of the module you should: Have been reminded about those aspects of equilibrium thermodynamics most often referred to in this module; Understand the physics of diffusive processes. Know the origin of the Langevin and Diffusion equations and the key elements of these two descriptions; Have been introduced to the statistical mechanics of long chain molecules (polymers).Appreciate that this is an example of a system driven by configurational entropy rather than energy; Appreciate the importance of phase transitions via simple examples, primarily the paramagnetic-ferromagnetic transitIon; Understand the motivation behind the Ginzburg-Landau theory of continuous symmetry breaking phase transitions and have seen how it is solved; Understand the origin of the law of equipartition of energy and see how it may be used to solve real problems where we are interested in the statistics of fluctuations.

###### Other essential notes

Fluctuations play an essential role in nature. Statistical mechanics is, in essence, a description of the role played by these fluctuations. The module studies the physics of such seemingly diverse problems as diffusion, phase transitions and Fermi-Dirac and Bose-Einstein statistics. It also uses examples from Polymer physics where the behaviour of the polymer chains is driven by configurational entropy, rather than energy.
