Course Outline  Module Content
The detailed syllabus and tentative schedule are given here , only the key elements are listed below; 
 Thermodynamics: 0th,1st,2nd,3rd laws. Concept of temperature and entropy.
 Thermodynamic potentials: Ideal gases. Heat engines. Reversible vs irreversible processes.
 Calculus: Gauss integrals. Gamma function (generalisatin of factorial). Saddlepoint approximation. EulerMaclaurin resummation.
 Certain elements of cominatorics and probability theory.
 Foundations of statistical physics. Probabilistic description of statistical systems. Microcanonical, canonical, and grand canonical ensembles. Partition function. Derivation of thermodynamics from statistical physics. Boltzmann and Gibbs approaches to entropy.
 Applications of thermodynamics and statistics in physical systems.
In this course we will study macroscopic systems, i.e. systems that consist of very large number of smaller ones. Because of the large number of components, they acquire new significant properties which do not exist on the level of single particles. The main such property is existence of the function called entropy and of the second law of thermodynamics which states that entropy always increases. Our main goal would be to master these concepts and understand how they emerge from the microscopic description, i.e. from classical or quantum mechanics, when it is applied to the system with very large number of components. On the way we will learn a lot of interesting math, encounter several exciting physical phenomena.

Suggested Reading:
 Any standard book, to use for background reading, there is no shortage of choices. E.g: Kerson Huang, 'Introduction to Statistical Physics'
 L.D. Landau, E.M. Lifshitz, 'Statistical Physics' (good to read starting from December and later on as MA3444 followup)
 Module Prerequisite

MAU23402
 Assessment Detail

This module will be examined in a 2hour examination in Michaelmas term. The continuous assessment contributes 20% to the final annual mark. Reassessments if required will consist of 100% exam.
