Twist operator correlation functions in O(n) loop models
Jacob J. H. Simmons, John Cardy
Using conformal field theoretic methods we calculate correlation functions of geometric observables in the loop representation of the O(n) model at the critical point. We focus on…
Discretely Holomorphic Parafermions and Integrable Loop Models
Yacine Ikhlef, John Cardy
We define parafermionic observables in various lattice loop models, including examples where no Kramers-Wannier duality holds. For a particular rhombic embedding of the lattice in…
Inhomogeneous Quantum Quenches
Spyros Sotiriadis, John Cardy
We study the problem of a quantum quench in which the initial state is the ground state of an inhomogeneous hamiltonian, in two different models, conformal field theory and ordinar…
Conformal Field Theory and Statistical Mechanics
John Cardy
The lectures provide a pedagogical introduction to the methods of CFT as applied to two-dimensional critical behaviour.
