Erratum: Detectability of Dissipative Motion in Quantum Vacuum via Superradiance [Phys. Rev. Lett.96, 200402 (2006)]

Le résumé fourni par la source

The dissipated power for FBAR devices that appears in the first paragraph on page 4 of our Letter [1] is based on the modulation depth of 10 9 and 10 3 kg=m 3 , rather than the reported values of 10 8 and 3:3 10 3 kg=m 3 , with all other parameters unchanged. The stated 10 W damage threshold holds for an FBAR device of surface area of 250 m 250 m. Since the threshold power is expected to scale proportionally to the surface area, a 1 cm 2 area FBAR device as considered in the discussion would suffer no damage even if driven to a modulation depth of 10 8 . Moreover, a mechanical quality factor 48 times higher has been reported since then
