Abstract

In IQFT, a standard approach to compute correlation functions is the form factor bootstrap. The form factors satisfy some axioms, which can help us solve the form factors. Recently, this approach was used in TTbar-deformed IQFT by considering the CDD factor deformation. Through the well-known “replica-trick”, we solve the form factor bootstrap axioms for the branch-point twist fields and obtain the deformed twist fields form factors. Using these deformed form factors, we compute the deformed entanglement entropy in TTbar deformed IQFT up to two particle contributions. We find that the UV behavior of the entanglement entropy is changed drastically.

      On the universal behavior of TTbar-deformed CFTs | Joint HEP-TH Seminar

      AbstractThe torus partition function of TTbar-deformed CFTs is modular invariant. Using this fact, it is shown that TTbar-deformed CFTs exhibit a universal free energy in the high temperature limit and a universal spectrum in the high energy limit. In this work, we show that a much stronger form of universality holds in TTbar-deformed CFTs with a large central charge c for both the double and s...

      The form factor program: asymptotic factorization of n-particle SU(N) form factors

      AbstractWe investigate the high energy behavior of the SU(N) chiral Gross-Neveu model in 1 + 1 dimensions. The model is integrable and matrix elements of several local operators (form factors) are known exactly. The form factors show rapidity space clustering, which means factorization, if a group of rapidities is shifted to infinity. We analyze this phenomenon for the SU(N) model. For several ...
