A macroscopic object passively cooled into its quantum ground state of motion beyond single-mode cooling

Autor: D. Cattiaux, I. Golokolenov, S. Kumar, M. Sillanpää, L. Mercier de Lépinay, R. R. Gazizulin, X. Zhou, A. D. Armour, O. Bourgeois, A. Fefferman, E. Collin

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-6 (2021)

Compared to active techniques, passive cooling of mechanical modes allows to work with devices in equilibrium with their environment without excess damping. Here, the authors demonstrate passive cooling and thermalisation of a 15 μm drum-head device

We explore the nonlinear dynamics of a cavity optomechanical system. Our realization consisting of a drumhead nanoelectromechanical resonator (NEMS) coupled to a microwave cavity allows for a nearly ideal platform to study the nonlinearities arising

Autor: A. I. Laskin, Alex Klochkov, R. R. Gazizulin, M. S. Tagirov, E. I. Kondratyeva, E. M. Alakshin

Publikováno v: Applied Magnetic Resonance. 48:723-729

Geological samples of calcium carbonates (CaCO3) were investigated by 3He NMR, nitrogen porosimetry, X-ray diffraction and electron microscopy methods. The integral porosity of the samples was obtained by 3He nuclear magnetic resonance method and com

Physical Review Applied, 2019, 12 (4), pp.044066. ⟨10.1103/PhysRevApplied.12.044066⟩

We report on microwave optomechanics measurements performed on a nuclear adiabatic demagnetization cryostat, whose temperature is determined by accurate thermometry from below 500$~\mu$K to about 1$~$Kelvin. We describe a method for accessing the on-

Publikováno v: Physical Review B. 100

Superfluids, such as superfluid 3He and 4He, exhibit a broad range of quantum phenomena and excitations which are unique to these systems. Nanoscale mechanical resonators are sensitive and versatile force detectors with the ability to operate over ma
