• Title: Quantum recurrences in the kicked top
• Authors: Amit Anand, Jack Davis and Shohini Ghose
• Abstract summary: We present an infinite family of quantum dynamics that never resembles the analogous classical chaotic dynamics irrespective of dimension. Because these state-independent temporal periodicities are present in all dimensions, their existence represents a universal violation of the correspondence principle. We discuss the relationship of these periodicities with the quantum kicked rotor, in particular the phenomenon of quantum anti-resonance.

• Abstract: The correspondence principle plays an important role in understanding the emergence of classical chaos from an underlying quantum mechanics. Here we present an infinite family of quantum dynamics that never resembles the analogous classical chaotic dynamics irrespective of dimension. These take the form of stroboscopic unitary evolutions in the quantum kicked top that act as the identity after a finite number of kicks. Because these state-independent temporal periodicities are present in all dimensions, their existence represents a universal violation of the correspondence principle. We further discuss the relationship of these periodicities with the quantum kicked rotor, in particular the phenomenon of quantum anti-resonance.

• Probing quantum chaos with the entropy of decoherent histories [0.0]
  Quantum chaos, a phenomenon that began to be studied in the last century, still does not have a rigorous understanding. We propose the quantum chaos definition in the manner similar to the classical one using decoherent histories as a quantum analogue of trajectories. We show that for such a model, the production of entropy of decoherent histories is radically different in integrable and chaotic regimes.
