概要

ABSTRACT)

We show that rapid growth of information metric of Thermofield double stateis directly related to commutator of simple operators. Following holographic proposal for information metric, we compute information metric of thermofield double state for marginal deformation, by evaluating volume of maximal volume codimension 1 surface, and confirm that information metric increases exponentially with time. Our result implies thermofield double state of chaotic system is sensitive to change of outer environment. We note that our holographic calculation of information metric is consistent with the expected decay of two point function of spacial Wilson loops on great circle.
