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
