摘要
The TTbar deformation is a special type of "solvable" deformation. When applied to CFTs, the deformed theory shows signs of nonlocality and can be further reformulated as a string theory. Under this framework, we develop worldsheet techniques to compute its entanglement entropy via a generalization of the replica trick in string theory. The result hints at a process where nonlocality is gradually introduced through the deformation and finally smooths out the UV cutoff of the original CFT. The talk will be based on arxiv:2507.15220.
