A Toy Model for Topological Entanglement Features in 1+1D Integrable Quantum Field Theory
Emmalise J. H. Aalbers, Olalla A. Castro-Alvaredo
In this paper we investigate an entanglement measure, the Rényi entropy, in a 1+1D integrable quantum field theory known as the Federbush model. This is a deformation of the theor…
Entanglement Asymmetry in Random Quantum Automata
Olalla A. Castro-Alvaredo, Dávid Szász-Schagrin, Michele Mazzoni
We investigate the subsystem entanglement asymmetry in random quantum automaton ensembles, which are generated by permuting the basis states in the Hilbert space and applying globa…
Temporal Entanglement in Quantum Field Theory
Olalla A. Castro-Alvaredo
In this paper I propose a branch point twist field approach to computing a temporal entropy, that is, an entanglement measure across different time regions, as opposed to the usual…
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…
