Ion-laser-like interaction in optomechanical systems with Kerr nonlinearities
I. Ramos-Prieto, R. Román-Ancheyta, J. Récamier +2
Introducing a Kerr medium in a cavity coupled to a harmonically moving mirror, we reproduce known and solvable interactions such as two-coupled harmonic oscillators and ion-laser l…
Noise-Assisted Discord-Like Correlations in Light-Harvesting Photosynthetic Complexes
Pablo Reséndiz-Vázquez, Ricardo Román-Ancheyta, Roberto de J. León-Montiel
Transport phenomena in photosynthetic systems have attracted a great deal of attention due to their potential role in devising novel photovoltaic materials. In particular, energy t…
Quantum transport in non-Markovian dynamically-disordered photonic lattices
Ricardo Román-Ancheyta, Barış Çakmak, Roberto de J. León-Montiel +1
We theoretically show that the dynamics of a driven quantum harmonic oscillator subject to non-dissipative noise is formally equivalent to the single-particle dynamics propagating…
Enhanced steady-state coherence via repeated system-bath interactions
Ricardo Román-Ancheyta, Michal Kolář, Giacomo Guarnieri +1
The appearance of steady-state coherence (SSC) from system-bath interaction proves that quantum effects can appear without an external drive. Such SSC could become a resource to de…
Spectral signatures of non-thermal baths in quantum thermalization
Ricardo Román-Ancheyta, Barış Çakmak, Özgür E. Müstecaplıoğlu
We show that certain coherences, termed as heat-exchange coherences, which contribute to the thermalization process of a quantum probe in a repeated interactions scheme, can modify…
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…
Tailoring the thermalization time of a cavity-field using distinct atomic reservoirs
Deniz Türkpençe, Ricardo Román-Ancheyta
We study how the thermalization time of a single radiation cavity-field mode changes drastically depending on the type of the atomic reservoir it interacts. Temporal evolution of t…
Large time-asymmetric quantum fluctuations in amplitude-intensity correlation measurements of a V-type three-level atom resonance fluorescence
L. Gutiérrez, H. M. Castro-Beltrán, R. Román-Ancheyta +1
In this paper we show that the scattered field of a bichromatically driven V-type three-level atom exhibit asymmetry and large violation of classical bounds in amplitude-intensity…
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…
Ladder operators and coherent states for the trigonometric Pöschl-Teller potential
R. Román-Ancheyta, O de los Santos-Sánchez, J. Récamier
In this work we make use of deformed operators to construct the coherent states of some nonlinear systems by generalization of two definitions: i) As eigenstates of a deformed anni…
Parametric oscillator in a Kerr medium: evolution of coherent states
R. Román-Ancheyta, M. Berrondo, J. Récamier
We study the temporal evolution of a coherent state under the action of a parametric oscillator and a nonlinear Kerr-like medium. We make use of the interaction picture representat…
Photon added nonlinear coherent states for a one mode field in a Kerr medium
R. Román-Ancheyta, C. González Gutiérrez, J. Récamier
We construct Deformed Photon Added Nonlinear Coherent States (DPANCSs) by application of the deformed creation operator upon the Nonlinear Coherent States obtained as eigenstates o…
