Renormalization group in statistical mechanics: (1) rescaling of parameters and (2) calculating the free energy 3 Rescaling of effective hamiltonian coupling constants in the Wilsonain renormalization group These classes are called Universality Classes and a major problem in equilibrium statistical mechanics is to characterise these classes. The Renormalization Group. Chapter 7. In this lecture, Prof. Kardar introduces the Perturbative Renormalization Group, including the Expectation Values in the Gaussian Model, Expectation Values in Perturbation Theory, Diagrammatic Representation of Perturbation Theory, and Susceptibility. The modern formulation of the renormalization group is explained for both critical phenomena in classical statistical mechanics and quantum field theory. Chapter 2. Chapter 3. Ideal Systems.

This problem set is partly intended to introduce the transfer matrix method, which is used to solve a variety of one-dimensional models with near-neighbor interactions.
