Boosting Gravity-Induced Entanglement through Parametric Resonance
Yuka Shiomatsu, Youka Kaku, Akira Matsumura +1
Establishing quantum gravity theory remains one of the major challenges in modern physics, as the lack of experimental evidence makes it difficult to explore. In response to this c…
Toward graviton detection via photon-graviton quantum state conversion
Taiki Ikeda, Youka Kaku, Sugumi Kanno +1
A magnetic field enables the interconversion of photons and gravitons, yet the process is usually analysed only at the level of classical wave equations. We revisit photon-graviton…
Sudden Decoherence by Resonant Particle Excitation for Testing Gravity-Induced Entanglement
Youka Kaku, Akira Matsumura, Tomohiro Fujita
We propose a novel method to probe gravity-induced entanglement. We consider the gravitational interaction between a particle trapped in a shallow potential and a harmonic oscillat…
Gravitational entanglement witness through Einstein ring image
Youka Kaku, Yasusada Nambu
We investigate the interplay between quantum theory and gravity by exploring gravitational lensing and Einstein ring images in a weak gravitational field induced by a mass source i…
Observing black holes through holographic superconductors
Youka Kaku, Keiju Murata, Jun Tsujimura
We propose a way to observe the photon ring of the asymptotically anti-de Sitter black hole dual to a superconductor on the two-dimensional sphere. We consider the electric current…
