Mechanical resonators are widely used in sensors, transducers and optomechanical
systems, where mechanical dissipation sets the ultimate limit to performance. Over the past …

We study the mechanical properties of stoichiometric SiN resonators through a combination
of spectroscopic and interferometric imaging techniques. At room temperature, we …

We have measured the thermal properties of suspended membranes from 10 to 300 K for
two amplitudes of internal stress (about 0.1 and 1 GPa) and for two different thicknesses (50 …

This paper reviews some of the key enabling technologies for advanced and future laser
interferometer gravitational wave detectors, which must combine test masses with the lowest …

Thermal noise associated with the mechanical loss of current highly reflective mirror
coatings is a critical limit to the sensitivity of gravitational-wave detectors. Several alternative …

The specific heat of phonon cavities is investigated in order to analyze the effect of phonon
confinement on thermodynamic properties. The specific heat of freestanding very thin SiN …

The thermal and acoustic properties displayed by a wide variety of glasses at low
temperatures are well described by the model of tunneling two-level systems (TLS). We …

Langevin dynamical simulations are performed to investigate the dislocation internal friction
(IF) of solid two-dimensional (2D) dusty plasmas under oscillating shear deformations. The …

Predicted by Einstein's General Theory of Relativity, gravitational waves are periodic
fluctuations in the curvature of space-time that propagate at the speed of light and are …

We propose a test method to study the effects of strain on the thermal conductivity of thin
films. First, a strain setup was designed to apply stress to a thin film, and a test system was …
