 It is often the case that the quantum chaology literature uses a broader notion of chaos as behavior that “cannot be described as a superposition of independent one-dimensional motions” (Ponomarenko, et al. 2008, p. 357); in other words, a form of inseparability. Still, the chaology in interacting quantum systems looks to be the same as in isolated systems: “Quantum mechanically, chaotic systems are characterized by distinctive statistics of their energy levels, which must comply with one of the Gaussian random ensembles, in contrast to the level statistics for the nonchaotic systems described by the Poisson distribution” (Ponomarenko, et al. 2008, p. 357). This is largely due to the fact that quantum chaology is closely tied to universal statistical patterns in quantum systems that share some relationship with classical chaotic counterpart systems.
