Non-monotonicity in the quantum-classical transition: Chaos induced by quantum effects
The transition from classical to quantum behavior for chaotic systems is
understood to be accompanied by the suppression of chaotic effects as the
relative size of is increased. We show evidence to the contrary in the
behavior of the quantum trajectory dynamics of a dissipative quantum chaotic
system, the double-well Duffing oscillator. The classical limit in the case
considered has regular behavior, but as the effective is increased we
see chaotic behavior. This chaos then disappears deeper into the quantum
regime, which means that the quantum-classical transition in this case is
non-monotonic in .Comment: 4 pages; presentation modified significantly to demonstrate that
quantum effects are indeed responsible for the `anomalous' chaos. 2 figures
