Specific Heat of Thin Phonon Cavities at Low Temperature: Very High Values Revealed by ZeptoJoule Calorimetry
Adib Tavakoli, Kunal J. Lulla, Tuomas Puurtinen +4
Specific heat of phonon cavities is investigated in order to analyse the effect of phonon confinement on thermodynamic properties. The specific heat of free standing very thin SiN…
Inducing micromechanical motion by optical excitation of a single quantum dot
Jan Kettler, Nitika Vaish, Laure Mercier de Lépinay +11
Hybrid quantum optomechanical systems offer an interface between a single two-level system and a macroscopical mechanical degree of freedom. In this work, we build a hybrid system…
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…
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…
Specific Heat Signature of the Berezinskii-Kosterlitz-Thouless Transition in Ultrathin Superconducting Films
T. D. Nguyen, A. Frydman, O. Bourgeois
The Berezinskii-Kosterlitz-Thouless (BKT) transition is expected to have a clear signature on the specific heat. The singularity at the transition temperature is predicte…
Niobium nitride thin films for very low temperature resistive thermometry
Tuyen Nguyen, Adib Tavakoli, Sebastien Triqueneaux +10
We investigate thin film resistive thermometry based on metal-to-insulator-transition (niobium nitride) materials down to very low temperature. The variation of the NbN thermometer…
