Recent Developments in the Holographic Description of Quantum Chaos

Figure 14

Illustration of the entangling surfaces in the slice of a two-sided black brane geometry. The U-shaped surfaces ( and ) are represented by blue curves. The surface stretching through the wormhole is given by the union of the two red surfaces . In the left panel we represent the unperturbed geometry, in which the two horizons coincide. In the right panel we represent the geometry in the presence of a shock wave added at some time in the past. In this case the size of the wormhole is effectively larger, and the two horizons no longer coincide.
