The Challenge of Detecting Quantum Nature of Gravitational Waves

Yu Miyauchi, Hidetoshi Omiya, Atsuhisa Ota +2

We investigate whether squeezing can provide an observable signature of quantum gravitational waves. Because a realistic detector couples only to a particular wave-packet mode, squ…

Scalar polarization window in gravitational-wave signals

Hiroki Takeda, Yusuke Manita, Hidetoshi Omiya +1

Scalar polarization modes of gravitational waves, which are often introduced in the context of the viable extension of gravity, have been actively searched. However, couplings of t…

Pathology in WKB wave function for tunneling assisted by gravity

Stefano Ansoldi, Takahiro Tanaka

There are several exotic tunneling processes that can be realized only by incorporating the effect of gravity. Here, we point out that we encounter difficulties in constructing the…

Impact of multiple modes on the evolution of self-interacting axion condensate around rotating black holes

Hidetoshi Omiya, Takuya Takahashi, Takahiro Tanaka +1

Ultra-light particles, such as axions, form a macroscopic condensate around a highly spinning black hole by the superradiant instability. Due to its macroscopic nature, the condens…

Resonant jumps induced by stationary tidal perturbation: a two-for-one deal

Priti Gupta, Takafumi Kakehi, Takahiro Tanaka

Extreme-mass-ratio inspirals (EMRIs) are promising target sources for space-based interferometers such as LISA, Taiji, and Tianqin. Depending on the astrophysical environment, such…

Assessing the impact of non-Gaussian noise on convolutional neural networks that search for continuous gravitational waves

Takahiro S. Yamamoto, Andrew L. Miller, Magdalena Sieniawska +1

We present a convolutional neural network that is capable of searching for continuous gravitational waves, quasi-monochromatic, persistent signals arising from asymmetrically rotat…
