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…
Observing axions through photon ring dimming of black holes
Kimihiro Nomura, Kaishu Saito, Jiro Soda
It is known that magnetic fields exist near black holes and photons can go around black holes due to strong gravity. Utilizing these facts, we can probe hypothetical pseudoscalar p…
Impact of quantum entanglement induced by magnetic fields on primordial gravitational waves
Sugumi Kanno, Ann Mukuno, Jiro Soda +1
There exist observational evidence to believe the existence of primordial magnetic fields generated during inflation. We study primordial gravitational waves (PGWs) during inflatio…
Anisotropic warm inflation
Sugumi Kanno, Ann Mukuno, Jiro Soda +1
Anisotropic inflation is a model succeeded in explaining statistical anisotropy. Warm inflation is a model succeeded in providing a mechanism of reheating during inflation. We stud…
Conversion of squeezed gravitons into photons during inflation
Sugumi Kanno, Jiro Soda, Kazushige Ueda
It is believed that relic gravitons are squeezed during inflation. If so, quantum noise induced by them can be significantly enhanced in current interferometers. However, decoheren…
Geometric structure of multi-form-field isotropic inflation and primordial fluctuations
Chong-Bin Chen, Jiro Soda
An inflationary scenario is expected to be embedded into an ultraviolet (UV) complete theory such as string theory. The effect of UV complete theories may appear as nontrivial kine…
