Violation of the Leggett-Garg inequality in photon-graviton conversion
Kimihiro Nomura, Akira Taniguchi, Kazushige Ueda
The Leggett-Garg inequality (LGI) is a temporal analogue of Bell's inequality and provides a quantitative test of the nonclassicality of a system through its violation. We analytic…
Binary gravitational waves as probes of quantum graviton states
Sugumi Kanno, Jiro Soda, Akira Taniguchi
It is well known that the most reliable way to reveal the quantum nature of light is through photon number statistics, since photons exhibiting sub-Poissonian statistics unambiguou…
Coherent State Description of Gravitational Waves from Binary Black Holes
Sugumi Kanno, Jiro Soda, Akira Taniguchi
Quantum mechanics is the fundamental framework of nature, and gravitational waves from binary black holes during the inspiral phase should likewise be analyzed quantum mechanically…
Parity violation in photon quasinormal modes of black holes
Sugumi Kanno, Jiro Soda, Akira Taniguchi
Given that black holes are ubiquitous in the universe and axion-like scalar fields are potential candidates for dark energy and/or dark matter, it is natural to consider cosmologic…
Search for high-frequency gravitational waves with Rydberg atoms
Sugumi Kanno, Jiro Soda, Akira Taniguchi
We propose high-frequency gravitational wave (GW) detectors with Rydberg atoms. Rydberg atoms are ultra-sensitive detectors of electric fields. By setting up a constant magnetic fi…
