Nonequilibrium steady state fluctuations in actively cooled resonators
M. Bonaldi, L. Conti, P. De Gregorio +15
We analyze heat and work fluctuations in the gravitational wave detector AURIGA, modeled as a macroscopic electromechanical oscillator in contact with a thermostat and cooled by an…
Feedback cooling of the normal modes of a massive electromechanical system to submillikelvin temperature
A. Vinante, M. Bignotto, M. Bonaldi +13
We apply a feedback cooling technique to simultaneously cool the three electromechanical normal modes of the ton-scale resonant-bar gravitational wave detector AURIGA. The measurin…
Room temperature GW bar detector with opto-mechanical readout
L. Conti, M. De Rosa, F. Marin +2
We present the full implementation of a room-temperature gravitational wave bar detector equipped with an opto-mechanical readout. The mechanical vibrations are read by a Fabry--Pe…
Experimental measurement of photothermal effect in Fabry-Perot cavities
M. De Rosa, L. Conti, M. Cerdonio +2
We report the experimental observation of the photothermal effect. The measurements are performed by modulating the laser power absorbed by the mirrors of two high-finesse Fabry-Pe…
Wideband dual sphere detector of gravitational waves
M. Cerdonio, L. Conti, J. A. Lobo +3
We present the concept of a sensitive AND broadband resonant mass gravitational wave detector. A massive sphere is suspended inside a second hollow one. Short, high-finesse Fabry-P…
Thermoelastic effects at low temperatures and quantum limits in displacement measurements
M. Cerdonio, L. Conti, A. Heidmann +1
The displacement fluctuations of mirrors in optomechanical devices, induced via thermal expansion by temperature fluctuations due either to thermodynamic fluctuations or to fluctua…
