Superconducting aluminum heat switch with 3 n equivalent resistance
James Butterworth, Sébastien Triqueneaux, Šimon Midlik +9
Superconducting heat switches with extremely low normal state resistances are needed for constructing continuous nuclear demagnetization refrigerators with high cooling power. Alum…
Fully suspended nano-beams for quantum fluids
Ilya Golokolenov, Baptiste Alperin, Bruno Fernandez +2
Non-invasive probes are keystones of fundamental research. Their size, and maneuverability (in terms of e.g. speed, dissipated power) define their applicability range for a specifi…
Microwave optomechanical measurement of non-metallized SiN strings at mK temperatures
Sumit Kumar, Yannick Klaß, Baptiste Alperin +5
The mechanical properties of amorphous materials (glasses) at low temperatures are dominated by effects of low energy excitations that are thought to be atomic-scale tunneling two…
Developing compact tuning fork thermometers for sub-mK temperatures and high magnetic fields
Andrew J. Woods, Alexander. M. Donald, Rasul Gazizulin +2
There is a growing demand for experiments on calorimetric and thermal transport measurements at ultra-low temperatures below 1 mK and high magnetic fields up to 16 T. Particularly,…
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…
