Wide bandwidth dual acoustic gravitational wave detectors
In a “dual” detector a wideband sensitivity is obtained by measuring the differential displacement, driven by the gw wave, of the facing surfaces of two nested massive bodies mechanically resonating at different frequencies. By the use of the recently proposed “selective readout” scheme, capable of specifically selecting the signal contributed by the vibrational modes sensitive to the gravitati...
متن کاملParticle acoustic detection in gravitational wave aluminum resonant antennas
The results on cosmic rays detected by the gravitational antenna NAUTILUS have motivated an experiment (RAP) based on a suspended cylindrical bar, which is made of the same aluminum alloy as NAUTILUS and is exposed to a high energy electron beam. Mechanical vibrations originate from the local thermal expansion caused by warming up due to the energy lost by particles crossing the material. The a...

متن کاملExperimental demonstration of a classical analog to quantum noise cancellation for use in gravitational wave detection.
We present results that are a classical analog to quantum noise cancellation. It is possible to breach the standard quantum limit in an interferometer by the use of squeezing to correlate orthogonal quadratures of quantum noise, causing their effects on the resulting sensitivity to cancel. A laser beam incident on a Fabry-Perot cavity was imprinted with classical, correlated noise in the same q...
متن کاملGravitational Analog of the Electromagnetic Poynting Vector
The gravitational analog of the electromagnetic Poynting vector is constructed using the field equations of general relativity in the Hilbert gauge. It is found that when the gravitational Poynting vector is applied to the solution of the linear mass quadrupole oscillator, the correct gravitational quadrupole radiation flux is obtained. Further to this, the Maxwell-like gravitational Poynting v...
