Universal amplitude ratios in the two-dimensional -state Potts model and percolation from quantum field theory
G. Delfino, J. L. Cardy
We consider the scaling limit of the two-dimensional -state Potts model for . We use the exact scattering theory proposed by Chim and Zamolodchikov to determine the one…
Universal amplitude ratios in the two-dimensional Ising model
Gesualdo Delfino
We use the results of integrable field theory to determine the universal amplitude ratios in the two-dimensional Ising model. In particular, the exact values of the ratios involvin…
Non-integrable aspects of the multi-frequency Sine-Gordon model
G. Delfino, G. Mussardo
We consider the two-dimensional quantum field theory of a scalar field self-interacting via two periodic terms of frequencies and . Looking at the theory as a perturbed Sine…
Quasi-1D spin-1/2 Heisenberg magnets in their ordered phase: correlation functions
Fabian H. L. Essler, Alexei M. Tsvelik, Gesulado Delfino
We study weakly coupled antiferromagnetic spin chains in their ordered phase by combinining an exact solution of the single-chain problem with an RPA analysis of the interchain int…
