Phys. Rev. Lett. 80, 5524–5527 (1998)Quantum Dynamical Manifestation of Chaotic Behavior in the Process of EntanglementReceived 9 October 1997; published in the issue dated 22 June 1998 Manifestation of chaotic behavior is found in an intrinsically quantum property. The entanglement process, quantitatively expressed in terms of the reduced density linear entropy, is studied for the N-atom Jaynes-Cummings model. For a given energy, initial conditions are prepared as minimum uncertainty wave packets centered at regular and chaotic regions of the classical phase space. We find for short times a faster increase in decoherence for the chaotic initial conditions as compared to regular ones, which have oscillatory increase. © 1998 The American Physical Society URL:
