Mechanical loss in state-of-the-art amorphous optical coatings
Massimo Granata, Emeline Saracco, Nazario Morgado +9
We present the results of mechanical characterizations of many different high-quality optical coatings made of ion-beam-sputtered titania-doped tantala and silica, developed origin…
Measurements of mechanical thermal noise and energy dissipation in optical dielectric coatings
Tianjun Li, Felipe A. Aguilar Sandoval, Mickael Geitner +10
In recent years an increasing number of devices and experiments are shown to be limited by mechanical thermal noise. In particular sub-Hertz laser frequency stabilization and gravi…
A method to measure the resonance transitions between the gravitationally bound quantum states of neutrons in the GRANIT spectrometer
M. Kreuz, V. V. Nesvizhevsky, P. Schmidt-Wellenburg +21
We present a method to measure the resonance transitions between the gravitationally bound quantum states of neutrons in the GRANIT spectrometer. The purpose of GRANIT is to improv…
