Entanglement production in coupled chaotic systems: Case of the kicked tops

JN Bandyopadhyay, A Lakshminarayan - Physical Review E, 2004 - APS
Entanglement production in coupled chaotic systems is studied with the help of kicked tops.
Deriving the correct classical map, we have used the reduced Husimi function, the Husimi …

Quantum biology on the edge of quantum chaos

G Vattay, S Kauffman, S Niiranen - PloS one, 2014 - journals.plos.org
We give a new explanation for why some biological systems can stay quantum coherent for
a long time at room temperature, one of the fundamental puzzles of quantum biology. We …

Public-key encryption with chaos

L Kocarev, M Sterjev, A Fekete, G Vattay - Chaos: An Interdisciplinary …, 2004 - pubs.aip.org
Chaotic systems are characterized by sensitive dependence on initial conditions, similarity
to random behavior, and continuous broad-band power spectrum. The possibility for self …

Entanglement and its relationship to classical dynamics

JB Ruebeck, J Lin, AK Pattanayak - Physical Review E, 2017 - APS
We present an analysis of the entangling quantum kicked top focusing on the few qubit case
and the initial condition dependence of the time-averaged entanglement SQ for spin …

Chaos and dynamical complexity in the quantum to classical transition

B Pokharel, MZR Misplon, W Lynn, P Duggins… - Scientific reports, 2018 - nature.com
We study the largest Lyapunov exponents λ and dynamical complexity for an open quantum
driven double-well oscillator, mapping its dependence on coupling to the environment Γ as …

Tuning quantum measurements to control chaos

JK Eastman, JJ Hope, ARR Carvalho - Scientific reports, 2017 - nature.com
Environment-induced decoherence has long been recognised as being of crucial
importance in the study of chaos in quantum systems. In particular, the exact form and …

Environmental effects in the quantum-classical transition for the delta-kicked harmonic oscillator

ARR Carvalho, RL de Matos Filho, L Davidovich - Physical Review E …, 2004 - APS
We discuss the roles of the macroscopic limit and different system-environment interactions
in a quantum-classical transition for a chaotic system. We consider the kicked harmonic …

Quantum mechanics of Hyperion

N Wiebe, LE Ballentine - Physical Review A—Atomic, Molecular, and Optical …, 2005 - APS
This paper is motivated by the suggestion [W. Zurek, Phys. Scri. T, 76, 186 (1998)] that the
chaotic tumbling of the satellite Hyperion would become nonclassical within 20 years, but for …

Chaos in continuously monitored quantum systems: An optimal-path approach

P Lewalle, J Steinmetz, AN Jordan - Physical Review A, 2018 - APS
We predict that continuously monitored quantum dynamics can be chaotic. The optimal
paths between past and future boundary conditions can diverge exponentially in time when …

Quantum-classical transition of the open quartic oscillator: the role of the environment

AC Oliveira, JG Peixoto de Faria, MC Nemes - Physical Review E—Statistical …, 2006 - APS
We investigate the classical and quantum dynamics of the open quartic oscillator model.
Typically quantum behavior such as collapses and revivals (also squeezing) are induced by …
