A bstractWe study the evolution of the universal area law of entanglement entropy when the Hamiltonian of the system undergoes a time dependent perturbation. In particular, we derive a general formula for the time dependent first order correction to the area law under the assumption that the field theory resides in a vacuum state when a small time-dependent perturbation of a relevant coupling constant is turned on. Using this formula, we carry out explicit calculations in free field theories…

We study the entanglement entropy of theories that are derived from relevant perturbation of given CFTs for regions with a singular boundary by using the AdS/CFT correspondence. In the smooth case,

We calculate the time dependence of the reflected entropy of two disconnected regions after a global quench in $(1+1)$-dimensional conformal field theories. We focus on conformal field theories which
The holographic dual of Rényi relative entropy
Abstract The relative entropy is a measure of the distinguishability of two quantum states. A great deal of progress has been made in the study of the relative entropy between an excited state and
Evolution of complexity following a global quench
A bstractThe rate of complexification of a quantum state is conjectured to be bounded from above by the average energy of the state. A different conjecture relates the complexity of a holographic CFT
Divergences in the rate of complexification
TLDR
It is found that the rate of complexification according to both of these conjectures has UV divergences, whereas the instantaneous energy is UV finite, which implies that neither the \textit{complexity equals action} nor \text it{ complexity equals volume} conjecture is consistent with the conjectured bound on the rateof complexification.

Time evolution after double trace deformation
A bstractIn this paper, we consider double trace deformation to single CFT2, and study time evolution after the deformation. The double trace deformation we consider is nonlocal: composed of two

TLDR
Using the AdS/CFT correspondence, entanglement entropy for a boundary theory deformed by a relevant operator is examined and it is shown that the relevant deformation introduces new logarithmic contributions to the entangled entropy.
