Block course "Conformal Field Theory and Non-abelian Bosonization", EPFL

This webpage is used to distribute the lecture notes and exercises for the second part of the block course "Abelian and non-abelian bosonization for 1D quantum physics". [Official announcement]

Some more details about particular topics can be found in older lecture notes of mine from 2014 [Link]

  • Day 2: The energy momentum tensor T, conformal Ward identities, the OPE of T with itself and with primary fields, the central charge, operator formalism, radial quantization, state-field correspondence, in- and out-states, from OPEs to commutation relations [Notes]
  • Day 3: The Virasoro algebra, descendants, unitarity, Verma modules, irreducible modules, characters, Virasoro minimal models [Notes]
  • Day 4: The free fermion as a conformal field theory, current algebras, Sugawara construction [Notes]
