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...
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 ...
