Dynamical theory of quantum chaos or hidden random matrix ensemble?
Abstract
In a recent Letter [Phys.Rev.Lett., 77,4536 (1996), chao-dyn/9609014] Altland and Zirnbauer claim that they rigorously proved the complete analogy between a (classically chaotic) dynamical system and disordered (random) solids. The purpose of this Comment is to show that, in fact, their theory fails to take into account dynamical features which go beyond standard random matrix theory description.
