108. Detection of gravitational waves by electromagnetic cavity: a review

Gravitational Waves

Gravitational wave (GW) detection using electromagnetic (EM) cavities has garnered significant attention in recent years. With ongoing experiments on axion detection using highly sensitive electromagnetic cavity, there is potential to apply these existing facilities to GW detection, opening up a new channel of GW observation. In this review, we comprehensively examine the principles of GW...

66. Optimizing the geometry of axion haloscopes for gravitational wave searches

Sung Mook Lee (Yonsei University)

Cosmology

In the presence of electromagnetic fields, gravitational waves (GWs) induce oscillating magnetic fields proportional to the GW amplitude.

That the same is true for an axion implies that a synergy exists between the experimental effort to probe axion dark-matter and the search for high frequency GWs.

We derive selection rules which determine the parametric sensitivity of different...

12. Exploring the ultralight axion dark matter by the gravitational wave and radio telescopes

Prof. Fa Peng Huang (Sun Yat-sen University)

Gravitational Waves

We study the new observational effects of ultralight axion-like particles by the space-borne gravitational wave detector and the radio telescopes. Taking the neutron star-black hole binary as an example, we demonstrate that the phase of gravitational waveform could be obviously modified by the slow depletion of the axion cloud around the black hole formed through the superradiance process....

88. Sensitivity to Dark Sector Scales from Gravitational Wave Signatures

Sumit Ghosh (Korea Institute for Advanced Study)

Gravitational Waves

We consider gravitational sound wave signals produced by a first-order phase transition in a theory with a generic renormalizable thermal effective potential of power law form. We find the frequency and amplitude of the gravitational wave signal can be related in a straightforward manner to the parameters of the thermal effective potential. This leads to a general conclusion; if the mass of...

2. Observing ultralow-frequency gravitational waves with pulsar parameter drift

William DeRocco (University of California, Santa Cruz)

Gravitational Waves

Gravitational waves with frequencies below 1 nHz are notoriously difficult to detect, and experimental methodologies for their detection are lacking. In this talk, I will present a new means of probing this regime by using secular drifts in observed pulsar timing parameters. I will begin by presenting two complementary observables for which the systematic shift induced by ultralow-frequency...

69. Macroscopic Dark Matter Detection with Extreme Mass Ratio Inspirals and mini-EMRIs

Huaike Guo (University of Chinese Academy of Sciences)

15/06/2023, 18:30

Gravitational Waves

I will discuss the detection of macroscopic dark matter candidates such as primordial black holes, boson stars, etc, with a special kind of binary system, the extreme mass ratio inspirals, which is a main target for future space-based gravitational wave detectors, and emphasize its advantages in detection of subsolar exotic compact objects. I will also introduce the mini-EMRIs that can be...
