Dynamic Properties of Entanglement in Quantum Dicke Model

Gai Yong-Jie

Under the condition of classical limit,quantized Dicke model shows the dynamical behavior of quantum chaos.The numerical calculation shows that there are some particular points in the classical phase-space at which the quantum chaos is present.The impact of initial conditions of these particular positions on entanglement of the model was analyzed respectively under RWA(rotating-wave approximation) or non-RWA.The evolutionary characteristics of the overall dynamics were studied in the phase-space for all the phase points considered to be under the initial condition.The conclusion obtained is that classical chaos will accelerate the generation of entanglement.

Characterizing the dynamical phase diagram of the Dicke model via classical and quantum probes

R. J. Lewis-Swan, S. R. Muleady, D. Barberena +2 more

We theoretically study the dynamical phase diagram of the Dicke model in both classical and quantum limits using large, experimentally relevant system sizes.Our analysis elucidates that the model features dynamical critical points that are strongly influenced by features of chaos and emergent integrability in the model.Moreover, our numerical calculations demonstrate that mean-field features of the dynamics remain valid in the exact quantum dynamics, but we also find that in regimes where quantum effects dominate signatures of the dynamical phases and chaos can persist in purely quantum metrics such as entanglement and correlations.Our predictions can be verified in current quantum simulators of the Dicke model including arrays of trapped ions.
