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 Optomechanically Induced Transparency and Absorption Between 250 and 450 mK
Sumit Kumar, Dylan Cattiaux, Eddy Collin +2
High-quality microwave amplifiers and notch-filters can be made from microwave optomechanical systems in which a mechanical resonator is coupled to a microwave cavity by radiation…
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…
Nanomechanical damping via electron-assisted relaxation of two-level systems
Olivier Maillet, Dylan Cattiaux, Xin Zhou +4
We report on measurements of dissipation and frequency noise at millikelvin temperatures of nanomechanical devices covered with aluminum. A clear excess damping is observed after s…
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…
On-chip thermometry for microwave optomechanics implemented in a nuclear demagnetization cryostat
X. Zhou, D. Cattiaux, R. R. Gazizulin +7
We report on microwave optomechanics measurements performed on a nuclear adiabatic demagnetization cryostat, whose temperature is determined by accurate thermometry from below 500$…
