PHY2023 : Statistical Mechanics

Semester 2 Credit Value: 10
ECTS Credits: 5.0


To provide a knowledge and understanding of statistical mechanics and how this can be used to understand the behaviour of collections of large numbers of particles such as atoms, electrons, photons and phonons.

Outline Of Syllabus

Statistical interpretation of entropy. S = k lnĪ©. Boltzmann distribution, 2-level system, Einstein and Debye theories of specific heat. Black body radiation. Specific heats of a diatomic molecule. Maxwell Boltzmann velocity distribution. In distinguishability, Fermi-Dirac and Bose-Einstein distributions.

Teaching Rationale And Relationship

The lectures are the main means of delivering the knowledge base required for the module. The lecturer highlights the important aspects and enhances understanding through illustrative examples. Exercises relating to the lecture material are set at regular intervals to encourage the development of a deeper understanding of the topics and enhance skills in problem solving and mathematical manipulation. Private study consolidates the knowledge and understanding acquired during lectures. Confidence in understanding basic physics and key problem solving skills is established through solving a variety of problems that illustrate the physics involved.
Formative feedback is given following the marking of the set exercises.

Assessment Rationale And Relationship

Much of the material taught in the module is factual and the student is asked to demonstrate a knowledge and understanding of the content through being able to present the basic aspects of their knowledge of the material in an unseen written examination paper and to demonstrate an ability to manipulate numerical problems on the topics. Weekly exercises are set and assessed during the module to enhance the understanding of the material and nurture the progressive acquisition of skills in solving illustrative problems.
