Abstract

We study TT deformation, an irrelevant integrable deformation which non-trivially modifies the spectral properties in JT gravity. Even though it is an integrable deformation, it significantly alters the chaotic nature of the system, which is peculiar. We compute deformed partition functions and changes to the absorption/emission probabilities of baby universes. We study the saturation of complexity, making use of the ‘complexity = volume’ conjecture. We observe a faster saturation in the complexity profile compared to pure JT gravity. We also study the nature of a possible RMT dual to the deformed theory and observe how the action of ZZ branes is natural in the deformed theory.
