Quantum-classical correspondence of a field induced KAM-type transition: A QTM approach

Abstract

A transition from regular to chaotic behaviour in the dynamics of a classical Henon-Heiles oscillator in the presence of an external field is shown to have a similar quantum signature when studied using the pertaining phase portraits and the associated Kolmogorov-Sinai-Lyapunov entropies obtained through the corresponding Bohmian trajectories. © Indian Academy of Sciences.
