“…The experimental efforts are converging towards the possibility of direct detection of stochastically distributed gravitational waves [19,20]. Various resonant mass detectors are now operating at a typical frequency of the order of kHz (Allegro [21], Auriga [22], Explorer [23], Nautilus [24], Niobe [25]) and four Michelson interferometers (GEO-600 [26],TAMA-400 [27], LIGO [29] and VIRGO [28]) will soon be operating in a wide frequency band from a few Hz up to 10 kHz. It is interesting, in the context of ABBN, to elaborate on the possibility that the additional relativistic species are of gravitational origin.…”

Big bang nucleosynthesis, matter-antimatter regions, extra relativistic species, and relic gravitational waves

2002

Provided that matter-antimatter domains are present at the onset of big bang nucleosynthesis (BBN), the number of allowed additional relativistic species increases, compared to the standard scenario when matter-antimatter domains are absent. The extra relativistic species may take the form of massless fermions or even massless bosons, like relic gravitons. The number of additional degrees of freedom compatible with BBN depends, in this framework, upon the typical scale of the domains and the antimatter fraction. Since the presence of matter-antimatter domains allows a reduction of the neutron to proton ratio prior to the formation of 4 He, large amounts of radiation-like energy density are allowed. Our results are compared with other constraints on the number of supplementary relativistic degrees of freedom and with different nonstandard BBN scenarios where the reduction of the neutron to proton ratio occurs via a different physical mechanism. The implications of our considerations for the upper limits on stochastic gravitational waves backgrounds of cosmological origin are outlined.

“…Two key requirements to enter this quantum regime are the capacities to efficiently quantum control the oscillator and to achieve zeropoint-motion-limited transduction sensitivity. Strong electrical actuation of mechanical oscillators, an enabling step for quantum control, has been achieved in nanoelectromechanical systems (NEMS) [10][11][12][13][14][15][16]. Furthermore, transduction sensitivities near the quantum limit have been reached with cavity optomechanical systems (COMS) [17,18].…”

“…Furthermore, optical heating via optical absorption of intracavity power severely constrains the possibility of operation in the quantum regime [18]. By contrast, electrical actuation of NEMS is inherently strong, much less prone to heating effects, and comparatively straightforward to implement [10,12,13,15,30].…”

Cavity optoelectromechanical system combining strong electrical actuation with ultrasensitive transduction

et al. 2010

View full text Add to dashboard Cite

A cavity optoelectromechanical system is reported which combines the ultrasensitive transduction of cavity optomechanical systems with the electrical actuation of nanoelectromechanical systems. Ultrasensitive mechanical transduction is achieved via optomechanical coupling. Electrical gradient forces as large as 0.40 µN are realized, facilitating strong actuation with ultralow dissipation. A scanning probe microscope is implemented, capable of characterizing the mechanical modes. The integration of electrical actuation into optomechanical devices is an enabling step toward the regime of quantum nonlinear dynamics and provides capabilities for quantum control of mechanical motion.

“…Observation runs have already been performed in several interferometer (LIGO [1], VIRGO [2], GEO [3], TAMA [4], CLIO [5]) and resonator (ALLEGRO [6], EX-PLORER [7], NAUTILUS [8], AURIGA [9], NIOBE [10], MARIO SCHENBERG [11]) projects. In order of gravitational wave detection, the reduction of noise and fake triggers is crucial, since the gravitational wave amplitude and number of events are expected to be small and rare.…”

Effect of energy deposited by cosmic-ray particles on interferometric gravitational wave detectors

et al. 2008

View full text Add to dashboard Cite

We investigated the noise of interferometric gravitational wave detectors due to heat energy deposited by cosmic-ray particles. We derived a general formula that describes the response of a mirror against a cosmic-ray passage. We found that there are differences in the comic-ray responses (the dependence of temperature and cosmic-ray track position) in cases of interferometric and resonant gravitational wave detectors. The power spectral density of vibrations caused by low-energy secondary muons is 100-times smaller than the goal sensitivity of future second-generation interferometer projects, such as LCGT and Advanced LIGO. The arrival frequency of high-energy cosmic-ray muons that generate enough large showers inside mirrors of LCGT and Advanced LIGO is one per a millennium. We also discuss the probability of exotic-particle detection with interferometers.PACS numbers: 04.80. Nn, 95.35.+d, 95.55.Vj, 95.85.Ry
