Out-of-time-ordered correlators in a (T2)n/Zn CFT
Abstract
In this paper we continue analyzing the nonequilibrium dynamics in the (T2)n/Zn orbifold conformal field theory. We compute the out-of-time-ordered four-point correlators with twist operators. For rational η (=p /p') which is the square of the compactification radius, we find that the correlators approach nontrivial constants at late time. For n =2 they are expressed in terms of the modular matrices and for higher n orbifolds are functions of p p' and n . For irrational η , we find a new polynomial decay of the correlators that is a signature of an intermediate regime between rational and chaotic models.
