Single-Polariton Optomechanics [PDF]
Physical Review Letters, 2014 This paper investigates a novel hybrid cavity QED-optomechanics situation. We solve the Hamiltonian problem of a cavity coupled both to a two-level atom via a Jaynes-Cummings coupling and to a mechanical motion via radiation pressure coupling. The atom-cavity polariton number operator commutes with the total Hamiltonian leading to an exact analytical ...

Dynamical scattering models in optomechanics: Going beyond the 'coupled cavities' model [PDF]
, 2012 Recently [A. Xuereb, et al., Phys. Rev. Lett. 105, 013602 (2010)], we calculated the radiation field and the optical forces acting on a moving object inside a general one-dimensional configuration of immobile optical elements.

Vector optomechanical entanglement [PDF]
Nanophotonics, 2021 Abstract The polarizations of optical fields, besides field intensities, provide more degrees of freedom to manipulate coherent light–matter interactions. Here, we propose how to achieve a coherent switch of optomechanical entanglement in a polarized-light-driven cavity system.

Optomechanical Bell Test [PDF]
Physical Review Letters, 2018 Over the past few decades, experimental tests of Bell-type inequalities have been at the forefront of understanding quantum mechanics and its implications. These strong bounds on specific measurements on a physical system originate from some of the most fundamental concepts of classical physics-in particular that properties of an object are well ...

Cavity optomechanics with photonic bound states in the continuum
Physical Review Research, 2021 We propose a versatile, free-space cavity optomechanics platform built from two photonic crystal membranes, one of which is freely suspended, and designed to form a microcavity less than one wavelength long.

Tunable Transparency and Group Delay in Cavity Optomechanical Systems with Degenerate Fermi Gas
Photonics, 2023 We theoretically investigate the optical response and the propagation of an external probe field in a Fabry–Perot cavity, which consists of a mechanical mode of trapped, ultracold, fermionic atoms inside and simultaneously driven by an optical laser ...

Thermal noise and optomechanical features in the emission of a membrane-coupled compound cavity laser diode [PDF]
, 2016 We demonstrate the use of a compound optical cavity as linear displacement detector, by measuring the thermal motion of a silicon nitride suspended membrane acting as the external mirror of a near-infrared Littrow laser diode.

Ultralow-Noise SiN Trampoline Resonators for Sensing and Optomechanics
Physical Review X, 2016 In force sensing, optomechanics, and quantum motion experiments, it is typically advantageous to create lightweight, compliant mechanical elements with the lowest possible force noise.

Stroboscopic quantum optomechanics
Physical Review Research, 2020 We consider an optomechanical cavity that is driven stroboscopically by a train of short pulses. By suitably choosing the interpulse spacing we show that ground-state cooling and mechanical squeezing can be achieved, even in the presence of mechanical ...
