T(T)over bar deformation on multiquantum mechanics and regenesis

We study the T(T)over bar deformation on multiquantum mechanical systems. By introducing dynamical coordinate transformation, we reformulate the one-dimensional T(T)over bar deformation of generic quantum mechanical systems, which is consistent with the previous proposal in the literature. We further study the thermo-field-double state under the T(T)over bar deformation on these systems, which include the conformal quantum mechanical system, the Sachdev-Ye-Kitaev model, and the model satisfying the eigenstate thermalization hypothesis. We find common regenesis phenomena in which the signal injected into one local system can regenerate from the other local system. From the AdS(2)/CFT1 perspective, we study the deformation of Jackiw-Teitelboim gravity governed by Schwarzian action and find that these regenesis phenomena are realized by exchanging boundaries graviton via the nonlocal T(T)over bar coupling.
