Quantum signature of gravity in optomechanical systems with conditional measurement

Daisuke Miki, Akira Matsumura, Kazuhiro Yamamoto

We investigate the quantum signature of gravity in optomechanical systems under quantum control. We analyze the gravity-induced entanglement and squeezing in mechanical mirrors in…

Gravitational wave search through electromagnetic telescopes

Asuka Ito, Kazunori Kohri, Kazunori Nakayama

We study the graviton-photon conversion in the magnetic fields of the Earth, the Milky Way Galaxy, and intergalactic regions. Requiring that the photon flux converted from graviton…

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…

Exploring High Frequency Gravitational Waves with Magnons

Asuka Ito, Jiro Soda

Detecting gravitational waves with frequencies higher than 10 kHz requires new strategies. In previous papers, we proposed magnon gravitational wave detectors and gave the first li…

Probing primordial black holes with anisotropies in stochastic gravitational-wave background

Sai Wang, Valeri Vardanyan, Kazunori Kohri

Primordial black holes, if considered to constitute a significant fraction of cold dark matter, trace the inhomogeneous large-scale structure of the Universe. Consequently, the sto…
