Mutual Correlation in the Shock Wave Geometry

Abstract EN

We probe the shock wave geometry with the mutual correlation in a spherically symmetric Reissner-Nordström AdS black hole on the basis of the gauge/gravity duality.

In the static background, we find that the regions living on the boundary of the AdS black holes are correlated provided the considered regions on the boundary are large enough.

We also investigate the effect of the charge on the mutual correlation and find that the bigger the value of the charge is, the smaller the value of the mutual correlation will be.

As a small perturbation is added at the AdS boundary, the horizon shifts and a dynamical shock wave geometry form after long time enough.

In this dynamic background, we find that the greater the shift of the horizon is, the smaller the mutual correlation will be.

Especially for the case that the shift is large enough, the mutual correlation vanishes, which implies that the considered regions on the boundary are uncorrelated.

The effect of the charge on the mutual correlation in this dynamic background is found to be the same as that in the static background.
