Abstract

We investigate TTˉT\bar{T} deformation on non-Hermitian coupled Sachdev-Ye-Kitaev (SYK) model and the holographic picture. The relationship between ground state and thermofield double state is preserved under the TTˉT\bar{T} deformation. We prove that TTˉT\bar{T} deformed theory provides a reparameterization in large NN limit. These deformation effects is calculated numerically with green functions and free energy. The thermodynamic phase structures show the equivalence of the wormhole-black hole picture between non-Hermitian model and Hermitian model still holds under TTˉT\bar{T} deformation. We also study the correlation function in Lorentz time and revival dynamic.
