A macroscopic object passively cooled into its quantum ground state of motion: beyond single-mode cooling
D. Cattiaux, I. Golokolenov, S. Kumar +8
The building blocks of Nature, namely atoms and elementary particles, are described by quantum mechanics. This fundamental theory is the ground on which physicists have built their…
Microwave single-tone optomechanics in the classical regime
Ilya Golokolenov, Dylan Cattiaux, Sumit Kumar +4
We report on the quantitative experimental illustration of elementary optomechanics within the classical regime. All measurements are performed in a commercial dilution refrigerato…
Electric circuit model of microwave optomechanics
Xin Zhou, Dylan Cattiaux, Didier Theron +1
We report on the generic classical electric circuit modeling that describes standard single-tone microwave optomechanics. Based on a parallel RLC circuit in which a mechanical osci…
Beyond linear coupling in microwave optomechanics
D. Cattiaux, X. Zhou, S. Kumar +8
We explore the nonlinear dynamics of a cavity optomechanical system. Our realization consisting of a drumhead nano-electro-mechanical resonator (NEMS) coupled to a microwave cavity…
Geometrical Nonlinearity of Circular Plates and Membranes: an Alternative Method
D. Cattiaux, S. Kumar, X. Zhou +2
We apply the well-established theoretical method developed for geometrical nonlinearities of micro/nano-mechanical clamped beams to circular drums. The calculation is performed und…
