Phys. Rev. Lett. 101, 074101 (2008) [4 pages]Nonmonotonicity in the Quantum-Classical Transition: Chaos Induced by Quantum EffectsReceived 16 February 2007; published 11 August 2008 The classical-quantum transition for chaotic systems is understood to be accompanied by the suppression of chaotic effects as the relative ℏ 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 ℏ 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 nonmonotonic in ℏ. © 2008 The American Physical Society URL:
