X-ray signals converted from high-frequency gravitational waves emitted by spinning light primordial black hole dark matter
Asuka Ito, Kazunori Kohri
We investigate the detectability of high-frequency gravitational waves from the superradiance of light primordial black hole dark matter through photons converted in the Galactic m…
Graviton Floor
Himeka Matsuo, Asuka Ito, Kazunori Kohri +2
It has been observed that the Universe is permeated by the cosmic photon background, ranging from radio waves to gamma rays. We investigate the conversion of the photon background…
Gravitational waves from gaps of neutron stars
Akira Dohi, Asuka Ito, Shota Kisaka
The pulsar magnetosphere is a potential source of continuous gravitational waves due to the rapid charge-discharge process in short timescale, varying the electric-field energy den…
Quantum sensing of high-frequency gravitational waves with ion crystals
Asuka Ito, Ryuichiro Kitano, Wakutaka Nakano +1
A detection method for high-frequency gravitational waves using two-dimensional ion crystals is investigated. Gravitational waves can resonantly excite the drumhead modes of the io…
Graviton-photon conversion in blazar jets as a probe of high-frequency gravitational waves
Himeka Matsuo, Asuka Ito
We study graviton-photon conversion in the magnetic fields of a blazar jet and explore the possibility of detecting high-frequency gravitational waves through blazar observations.…
Quantum entanglement of ions for light dark matter detection
Asuka Ito, Ryuichiro Kitano, Wakutaka Nakano +1
A detection scheme is explored for light dark matter, such as axion dark matter or dark photon dark matter, using a Paul ion trap system. We first demonstrate that a qubit, constru…
Effects of Finite Material Size On Axion-magnon Conversion
So Chigusa, Asuka Ito, Kazunori Nakayama +1
Magnetic materials are particularly favorable targets for detecting axions interacting with electrons because the collective excitation of electron spins, the magnon, can be excite…
Macroscopic Quantum Response to Gravitational Waves
Asuka Ito, Ryuichiro Kitano
We study the excitation of a one-electron quantum cyclotron by gravitational waves. The electron in such as a penning trap is prepared to be at the lowest Landau level, which has a…
