Scaling law and stability for a noisy quantum system
Mark Sadgrove, Sandro Wimberger, Scott Parkins +1
We show that a scaling law exists for the near resonant dynamics of cold kicked atoms in the presence of a randomly fluctuating pulse amplitude. Analysis of a quasi-classical phase…
The initial momentum dependence of the quantum resonance in the delta-kicked rotor
J-A. Currivan, A. Ullah, M. D. Hoogerland
The influence of an initial momentum on the appearance of "quantum resonances" in the delta-kicked rotor system is explored experimentally. We show that for certain initial momenta…
Dissipation-driven quantum phase transitions in collective spin systems
S. Morrison, A. S. Parkins
We consider two different collective spin systems subjected to strong dissipation -- on the same scale as interaction strengths and external fields -- and show that either continuo…
Disentanglement of Source and Target and the Laser Quantum State
Changsuk Noh, H. J. Carmichael
Disentanglement of a laser source from its target qubit is proposed as a criterion establishing the laser quantum state as a coherent state. It is shown that the source-target dens…
Collective spin systems in dispersive optical cavity QED: Quantum phase transitions and entanglement
S. Morrison, A. S. Parkins
We propose a cavity QED setup which implements a dissipative Lipkin-Meshkov-Glick model -- an interacting collective spin system. By varying the external model parameters the syste…
Dynamical quantum phase transitions in the dissipative Lipkin-Meshkov-Glick model and proposed realization in optical cavity QED
S. Morrison, A. S. Parkins
We present an optical cavity QED configuration that is described by a dissipative version of the Lipkin-Meshkov-Glick model of an infinitely coordinated spin system. This open quan…
