Quantifying Strain and its Effect on Charge Transport in Ge/Si Core/Shell Nanowires
Aswathi K. Sivan, Nicolas Forrer, Aakash Shandilya +12
Strain engineering in semiconductor nanostructures offers a promising route to optimize electronic and optical properties for advanced quantum technologies. This study explores the…
Quantitative calibration of a TWPA applied to an optomechanical platform
Alexandre Delattre, Ilya Golokolenov, Richard Pedurand +11
In the last decade, the microwave quantum electronics toolbox has been enriched with quantum-limited detection devices such as Traveling Wave Parametric Amplifiers (TWPAs). The ext…
Aluminum goalpost nano-mechanical devices at low temperatures
Baptiste Alperin, Ilya Golokolenov, Gwénaëlle Julié +3
Mechanical objects have been widely used at low temperatures for decades, for various applications; from quantum fluids sensing with vibrating wires or tuning forks, to torsional o…
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…
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…
