Effective Action, Spectrum and First Law of Wedge Holography

Understand

In this paper, we study the effective action, the mass spectrum and the first law of entanglement entropy for a novel doubly holographic model called wedge holography.

• We work out the effective action of quantum gravity on the branes.
• In the perturbative formulation, it is given by an infinite sum of Pauli-Fierz actions.
• In the non-perturbative formulation, the effective action is composed of a higher derivative gravity and a matter action.
