Entanglement of a cavity with a three-level atom and a graphene membrane in the presence of a laser field

Alexandria Engineering Journal, 2023
This paper examines the entanglement and coherence of a hybrid quantum system in the presence of an external laser field. The hybrid system is composed of a single-mode cavity field containing a vibrating graphene membrane and a superconducting qutrit in

Mechanical entanglement via detuned parametric amplification

New Journal of Physics, 2014
We propose two schemes to generate entanglement between a pair of mechanical oscillators using parametric amplification. In contrast to existing parametric drive-based protocols, both schemes operate in the steady-state. Using a detuned parametric drive to maintain equilibrium and to couple orthogonal quadratures, our approach can be viewed as a two ...

Robust Sensing Based on Exceptional Points in Detuned Non-Hermitian Scattering System

Photonics
Non-Hermitian optics has revealed a series of counterintuitive phenomena with profound implications for sensing, lasing, and light manipulation. While the non-Hermiticity of Hamiltonians has been intensively investigated, recent advancements in the non ...

Long-lived entangled states in the double Jaynes–Cummings model taking into account the qubits direct dipole-dipole interaction

Физика волновых процессов и радиотехнические системы
Background. The study of entangled states in Jaynes–Cummings models and its multiqubit generalizations and extensions remains an important and relevant topic in modern quantum optics, quantum information science and solid state physics.

First operational dodecapole correction in the LHC

Physical Review Accelerators and Beams, 2023
Amplitude detuning measurements in the LHC have shown that a significant amount of detuning is generated via feed-down from high-order field errors in the magnets of the experiment insertion regions.

Detuning-dependent Properties and Dispersion-induced Instabilities of Temporal Dissipative Kerr Solitons in Optical Microresonators

, 2017
Temporal-dissipative Kerr solitons are self-localized light pulses sustained in driven nonlinear optical resonators. Their realization in microresonators has enabled compact sources of coherent optical frequency combs as well as the study of dissipative ...

Fast-slow mode coupling instability for coasting beams in the presence of detuning impedance

Physical Review Accelerators and Beams, 2020
A destabilizing effect of the detuning impedance has been recently observed in simulations of the CERN Proton Synchrotron (PS) at the injection energy: while without the detuning impedance the instability is faster in the vertical plane as expected (due ...

Detuning Optimization of Nonlinear Mistuned Bladed-Disks

Volume 8A: Structures and Dynamics — Aerodynamics Excitation and Damping; Bearing and Seal Dynamics; Emerging Methods in Engineering Design, Analysis, and Additive Manufacturing; Fatigue, Fracture, and Life Prediction, 2022
Abstract One major industrial challenge is to consider the detuning as a technological means to reduce the dynamical amplifications induced by mistuning. Due to technological evolutions, the nonlinear geometrical effects induced by the large displacements cannot longer be neglected.

On the Phases Structure of the Micromaser System [PDF]

, 1999
We investigate, in an exact manner, the phase structure of the micromaser system in terms of the physical parameters at hand like the atom cavity transit time, the atom-photon frequency detuning, the number of thermal photons and the probability for a ...

Frequency-Dependent Squeezing from a Detuned Squeezer

Physical Review Letters, 2022
Frequency-dependent squeezing is a promising technique to overcome the standard quantum limit in optomechanical force measurements, e.g., gravitational wave detectors. For the first time, we show that frequency-dependent squeezing can be produced by detuning an optical parametric oscillator from resonance.
