Phys. Rev. A 58, 2596–2599 (1998)Quantitative indicator for semiquantum chaosReceived 20 March 1998; published in the issue dated September 1998 By generalizing to a mixed-state environment the treatment recently given to a model advanced by Cooper et al. [Phys. Rev. Lett. 72, 1337 (1994)], we show that some characteristics of the so-called semiquantum chaos can be described by recourse to a special motion invariant of the problem, that thus becomes a chaos indicator. © 1998 The American Physical Society URL:
