Complete Minimal Form Factors for Irrelevant Deformations of Integrable Quantum Field Theory
Fabio Sailis, Olalla A. Castro-Alvaredo, Stefano Negro
In this paper, we present a method to compute the minimal form factors (MFFs) of diagonal integrable field theories perturbed by generalized perturbations. Building on e…

Time Evolution of the Symmetry Resolved Entanglement Entropy after a Mass Quench
Federico Rottoli, Michele Mazzoni, Fabio Sailis +1
In this paper we investigate the properties of the symmetry resolved entanglement entropy after a mass quench in the Ising field theory. Since the theory is free and the post-quenc…

Boundary Quantum Field Theories Perturbed by : Towards a Form Factor Program
Olalla A. Castro-Alvaredo, Stefano Negro, Fabio Sailis
Our understanding of irrelevant perturbations of integrable quantum field theories has greatly expanded over the last decade. In particular, we know that, from a scattering theory…
