Abstract: (APS)
We study a quantum information metric (or fidelity susceptibility) in conformal field theories with respect to a small perturbation by a primary operator. We argue that its gravity dual is approximately given by a volume of maximal time slice in an anti–de Sitter spacetime when the perturbation is exactly marginal. We confirm our claim in several examples.Note:
