    Thermal noise-limited beam balance as prototype of the Archimedes vacuum weight experiment and B-L dark photon search

    We describe the behavior of a beam balance used for the measurement of small forces, in macroscopic samples, in tens of mHz frequency band. The balance, which works at room temperature, is the prototype of the...

    Picoradiant tiltmeter and direct ground tilt measurements at the Sos Enattos site

    We report the tilt sensitivity reached by the ARCHIMEDES tiltmeter in the 2–20 Hz frequency region, where seismic noise is expected to give an important limitation to the sensitivity in the next future Gravita...

    Fiber-Optic Resonators for Strain-Acoustic Sensing and Chemical Spectroscopy

    Over the past several years, fiber-optic resonators have been used as mechanical probes by virtue of their intrinsic sensitivity to length changes, and chemical sensors based on sensitivity to molecular absorp...
