摘要
In this paper we continue analyzing the nonequilibrium dynamics in the (T-2)(n)/Z(n) orbifold conformal field theory. We compute the out-of-time-ordered four-point correlators with twist operators. For rational eta(= 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 pp' and n. For irrational., we find a new polynomial decay of the correlators that is a signature of an intermediate regime between rational and chaotic models.
