MATH4231: Statistical Mechanics IV

Please ensure you check the module availability box for each module outline, as not all modules will run in each academic year. Each module description relates to the year indicated in the module availability box, and this may change from year to year, due to, for example: changing staff expertise, disciplinary developments, the requirements of external bodies and partners, and student feedback.

Prerequisites

  • Analysis in Many Variables (MATH2031) AND [Mathematical Physics (MATH2071) OR Theoretical Physics 2 (PHYS2631)] AND additional Mathematical Sciences modules to the value of 60 credits in Levels 2 and 3, with at least 40 credits at Level 3.

Corequisites

  • None

Excluded Combinations of Modules

  • Foundations of Physics 3B (PHYS3631)
  • Foundations of Physics 4B (PHYS4261)

Aims

  • To develop a basic understanding of the dynamics and behaviour of systems with a large number of constituents.
  • To develop approximation techniques and calculational methods to understand collective dynamics of large particle ensembles.

Content

  • Thermal equilibrium, laws of thermodynamics, equations of
  • state, ideal gas law.
  • Probability distributions and random walks.
  • Classical statistical mechanics.
  • Distributions and identical particles.
  • Black-body radiation, magnetisation, neutron stars.
  • Phase transitions.
  • Reading material on one or more aspects of the
  • Renormalization Group.

Learning Outcomes

Subject-specific Knowledge:

  • The students will:
  • learn to deal with systems where statistical ideas give a good picture of the essential dynamics;
  • learn to develop approximation methods necessary to solve problems involving large systems;
  • master knowledge of the subject through one or more of the following subject areas: thermodynamics, probability distributions, statistical ensembles, phase transitions;
  • have a knowledge and understanding of a topic in the renormalization group approach.

Subject-specific Skills:

  • The students will have specialised knowledge and mathematical skills in tackling problems in: statistical modeling of large systems.
  • Ability to read independently to acquire knowledge and understanding of aspects of the Renormalization Group approach.
  • The students will have an appreciation of Statistical Mechanics and its utility in the real world in the study of various complex systems and solutions thereof.

Key Skills:

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

  • Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
  • Subject material assigned for independent study develops the ability to acquire knowledge and understanding without dependence on lectures.
  • Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
  • Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
  • The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
