Field Theory of Critical Phenomena

by G. Delfino (6 credits, type A)

4-state Potts model

Main topics

  • Spontaneous symmetry breaking, phase transitions and critical behavior
  • Scaling, renormalization and universality
  • Perturbative renormalization group
  • Universality classes (Ising, Potts, O(n), percolation, self-avoiding walks, …)
  • Quenched disorder and random critical points
  • Conformal and integrable field theories
  • Low-dimensional aspects (Kosterlitz-Thouless transition, continuously varying exponents, bosonization, …)
  • From exact S-matrices to correlation functions
  • Phase separation, interfaces and wetting
  • Comments are closed.
