Entangling operations in nonlinear two-atom Tavis-Cummings models
Rocío Gómez-Rosas, Carlos A. González-Gutiérrez, Juan Mauricio Torres
We derive an analytical approximate solution of the time-dependent state vector in terms of material Bell states and coherent states of the field for a generalized two-atom Tavis-C…
Distant emitters in ultrastrong waveguide QED: Ground-state properties and non-Markovian dynamics
Carlos A. González-Gutiérrez, Juan Román-Roche, David Zueco
Starting from the paradigmatic spin-boson model (SBM), we investigate the static and dynamical properties of a system of two distant two-level emitters coupled to a one-dimensional…
Wavefront prediction using artificial neural networks for open-loop Adaptive Optics
Xuewen Liu, Tim Morris, Chris Saunter +3
Latency in the control loop of adaptive optics (AO) systems can severely limit performance. Under the frozen flow hypothesis linear predictive control techniques can overcome this,…
Atomic Bell measurement via two-photon interactions
Carlos A. González-Gutiérrez, Juan Mauricio Torres
We introduce a complete Bell measurement on atomic qubits based on two photon interactions with optical cavities and discrimination of coherent states of light. The dynamical syste…
A Lie algebraic approach to a nonstationary atom-cavity system
C. A. González-Gutiérrez, O. de los Santos-Sánchez, R. Román-Ancheyta +2
In this work we study the generation of photons inside an ideal cavity with resonantly oscillating boundaries in the presence of a two-level atom. We make use of Lie algebraic tech…
Damped Casimir radiation and photon correlation measurements
R. Román-Ancheyta, O. de los Santos-Sánchez, C. González-Gutiérrez
An effective toy model for an ideal one-dimensional nonstationary cavity is taken to be the starting point to derive a fitting markovian master equation for the corresponding leaky…
Nonlinear Jaynes-Cummings model for two interacting two-level atoms
O. de los Santos-Sánchez, C. González-Gutiérrez, J. Récamier
In this work we examine a nonlinear version of the Jaynes-Cummings model for two identical two-level atoms allowing for Ising-like and dipole-dipole interplays between them. The mo…
Relations between entanglement and purity in non-Markovian dynamics
C. González-Gutiérrez, R. Román-Ancheyta, Diego Espitia +1
Knowledge of the relationships among different features of quantumness, like entanglement and state purity, is important from both fundamental and practical viewpoints. Yet, this i…
Dynamical Casimir effect in a Kerr Cavity
R. Román-Ancheyta, C. González-Gutiérrez, J. Récamier
We study the dynamical Casimir effect in an electromagnetic cavity containing a Kerr medium. We obtain approximate expressions for the time evolution operator as well as for the nu…
