AbstractTTbar is a solvable irrelevant deformation that leads to interesting properties such as nonlocality. When applied to a CFT, the effects of TTbar can be studied via cutoff and glue-on holography. In this talk, we will first introduce the glue-on geometry, which reveals many interesting features of TTbar deformed CFTs that were previously inaccessible through cutoff holography. We then in...
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...
