GENERAL-METHOD FOR DEFORMING QUANTUM DYNAMICS INTO CLASSICAL DYNAMICS WHILE KEEPING H-FIXED

Using Weinberg's generalized nonlinear quantum dynamics [Ann. Phys. (N.Y.) 194, 336 (1989)], we propose a simple way to form an interpolative dynamical system that joins the classical and quantum regimes. By altering a dimensionless control parameter lambda is-an-element-of [0, 1], one can smoothly metamorphose quantum evolution into classical evolution, keeping the Hilbert-space dimension and physical constants unchanged. The method suggests an alternative approach to studies of dynamical chaos suppression in quantized classically chaotic systems.
