Gauss-Bonnet correction to Holographic thermalization: two-point functions, circular Wilson loops and entanglement entropy

Understand

We study the thermalization of a class of 4-dimensional strongly coupled theories dual to a 5-dimensional AdS-Vaidya spacetime with Gauss-Bonnet curvature corrections.

• We probe the thermalization using the two-point functions, the expectation values of circular Wilson loops and entanglement entropy.
• When boundary separation is small, we observe that the thermalization times of these observables have the weak dependence on the Gauss-Bonnet coupling constant $\alpha $.
• In addition, the growth rate of entanglement entropy density is nearly volume-independent.
