Prototype superfluid gravitational wave detector [PDF]
Physical Review D, 2021 We study a cross-shaped cavity filled with superfluid $^4$He as a prototype resonant-mass gravitational wave detector. Using a membrane and a re-entrant microwave cavity as a sensitive optomechanical transducer, we were able to observe the thermally excited high-$Q$ acoustic modes of the helium at 20 mK temperature and achieved a strain sensitivity of $

Electromagnetic detector for gravitational waves [PDF]
Physics Letters A, 1978 Abstract We analyze the mode of operation of a two-level parametric electromagnetic detector for gravitational waves which is tunable and potentially more sensitive than the mechanical antennas currently considered.

NEARBY STARS AS GRAVITATIONAL WAVE DETECTORS [PDF]
The Astrophysical Journal, 2015 Sun-like stellar oscillations are excited by turbulent convection and have been discovered in some 500 main sequence and sub-giant stars and in more than 12,000 red giant stars. When such stars are near gravitational wave sources, low-order quadrupole acoustic modes are also excited above the experimental threshold of detectability, and they can be ...

Journal of Physics: Conference Series, 2020 Abstract The search for direct detection of Gravitational Wave made a huge step forward in the years between 2015-2017. After the first detection signals from the coalescence of binary black hole systems, we had both the great success of the LISA pathfinder mission and the detection of the first event due to a neutron star - neutron star

New Journal of Physics, 2005 The existence of gravitational radiation is a prediction of Einstein's general theory of relativity. Gravitational waves are perturbations in the curvature of spacetime caused by accelerated masses. Since the 1960s gravitational wave detectors have been built and constantly improved.

Low-frequency terrestrial gravitational-wave detectors [PDF]
Physical Review D, 2013 Direct detection of gravitational radiation in the audio band is being pursued with a network of kilometer-scale interferometers (LIGO, Virgo, KAGRA). Several space missions (LISA, DECIGO, BBO) have been proposed to search for sub-Hz radiation from massive astrophysical sources.

A REVIEW OF GRAVITATIONAL WAVE DETECTORS [PDF]
Annual Review of Nuclear and Particle Science, 1997 ▪ Abstract This review is devoted to presenting the status of the experimental search of gravitational radiation. After a short history of the development of detectors, we present the state of the art for both resonant antennas and interferometers. The final section is devoted to possible future developments of both techniques.

Hearing Higgs with gravitational wave detectors [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 AbstractThe relic gravitational wave background due to tensor linear perturbations generated during Higgs inflation is computed. Both the Standard Model and a well-motivated phenomenological completion (that accounts for all the experimentally confirmed evidence of new physics) are considered. We focus on critical Higgs inflation, which improves on the

Laser-interferometric detectors of gravitational waves [PDF]
Classical and Quantum Gravity, 1993 A laser interferometric detector of gravitational waves is studied and a complete solution (to first order in the metric perturbation) of the coupled Einstein-Maxwell equations with appropriate boundary conditions for the light beams is determined. The phase shift, the light deflection and the rotation of the polarization axis induced by gravitational ...
