 The kind of behavior observed in quantum chaology involves the statistics of energy states in quantum systems that have some kind of relationship to classical chaotic systems (e.g., by quantizing the latter systems). Important features of classical chaos, such as SDIC and the period doubling route to chaos, appear to be absent from quantum systems. This situation has led to arguments that the correspondence principle between quantum and classical mechanics fails and that the former may be incomplete (Ford 1992).
