On the Representation of Minimal Form Factors in Integrable Quantum Field Theory
Olalla A. Castro-Alvaredo, Stefano Negro, István M. Szécsényi
In this paper, we propose a new representation of the minimal form factors in integrable quantum field theories. These are solutions of the two-particle form factor equations, whic…
The Generalised Born Oscillator and the Berry-Keating Hamiltonian
Francesco Giordano, Stefano Negro, Roberto Tateo
In this study, we introduce and investigate a family of quantum mechanical models in 0+1 dimensions, known as generalized Born quantum oscillators. These models represent a one-par…
Entanglement Entropy from Form Factors in -Deformed Integrable Quantum Field Theories
Olalla A. Castro-Alvaredo, Stefano Negro, Fabio Sailis
In two recent papers we have proposed a program of study which allows us to compute the correlation functions of local and semi-local fields in generalised $\mathrm{T}\bar{\mathrm{…
Form Factors and Correlation Functions of -Deformed Integrable Quantum Field Theories
Olalla A. Castro-Alvaredo, Stefano Negro, Fabio Sailis
The study of -perturbed quantum field theories is an active area of research with deep connections to fundamental aspects of the scattering theory…
Completing the Bootstrap Program for -Deformed Massive Integrable Quantum Field Theories
Olalla A. Castro-Alvaredo, Stefano Negro, Fabio Sailis
In recent years a considerable amount of attention has been devoted to the investigation of 2D quantum field theories perturbed by certain types of irrelevant operators. These are…
Topological Gauging and Double Current Deformations
Sergei Dubovsky, Stefano Negro, Massimo Porrati
We study solvable deformations of two-dimensional quantum field theories driven by a bilinear operator constructed from a pair of conserved currents . We propose a quan…
