# Module MA3443: Statistical Physics I

**Credit weighting (ECTS)**- 5 credits
**Semester/term taught**- Michaelmas term 2017-18
**Lecturer**- Prof Dmytro Volin. See http://www.maths.tcd.ie/~dvolin/statphys.html for additional information on this module.
**Contact Hours**- 11 weeks, 3 lectures including tutorials per week
**Learning Outcomes**-
- Explain the ideas of equilibrium thermodynamics and apply them to various systems.
- Demonstrate an understanding of how macroscopic equilibrium properties arise from the underlying microscopic physics.
- Show familiarity with the notion of ensembles and use the formalism of statistical physics.
- Include interactions systematically through appropriate expansions.
- Explain the concept of a first order phase transition.

On successful completion of this module students will be able to

**Suggested Literature**- 1. Kerson Huang,
*'Introduction to Statistical Physics'* - 2. L.D. Landau, E.M. Lifshitz,
*'Statistical Physics'* - 3. James P. Sethna,
*'Statistical Mechanics: Entropy, Order Parameters and Complexity'* - 4. Lectures of Leonard Susskind on YouTube

**Module Prerequisite**- MA2342 - Advanced Classical Mechanics II
**Assessment Detail**- This module will be examined in a 2-hour
**examination**in Trinity term.**Two homework assignments**will be given. One is devoted to solving exercises, another one is to perform a mini-research and to demonstrate in this way your comprehension of the subject. The assignments contribute 25% to the final annual mark. Supplemental exam if required will consist of 100% exam.
