Photon evolution through light-particle conversion in stochastic magnetic fields: Kramers--Kronig relations and universality
Wataru Chiba, Ryusuke Jinno, Kimihiro Nomura
We study photon conversion into light particles, such as dilatons, axions, and gravitons, induced by background magnetic fields, and formulate the resulting evolution in terms of t…
Reflection polarization of close binaries as a probe of axion dark matter birefringence
Tomoki Matsuoka, Kimihiro Nomura, Hidetoshi Omiya
We propose close binary polarimetry as a probe of birefringence induced by ultralight axion dark matter. In a close binary, reflection or scattering can generate a small linear pol…
Axion-photon conversion in stochastic magnetic fields
Wataru Chiba, Ryusuke Jinno, Kimihiro Nomura
We investigate axion-photon conversion in stochastic magnetic fields, focusing on the evolution of the photon intensity and polarizations induced by conversion into axions. Assumin…
Detecting Parity-Violating Gravitational Wave Backgrounds with Pulsar Polarization Arrays
Qiuyue Liang, Kimihiro Nomura, Hidetoshi Omiya
Pulsar timing arrays probe isotropic stochastic gravitational wave (GW) backgrounds in the nanohertz band but are insensitive to its parity-violating component. Motivated by recent…
Searching for dark photon dark matter from terrestrial magnetic fields
Kimihiro Nomura, Atsushi Nishizawa, Atsushi Taruya +1
We present a novel search for dark photon dark matter (DM) using terrestrial magnetic field measurements at frequencies below 100 Hz. Coherently oscillating dark photon DM can indu…
Signature of polarized ultralight vector dark matter in pulsar timing arrays
Kimihiro Nomura, Hidetoshi Omiya, Takahiro Tanaka
We investigate observational signatures of ultralight vector dark matter with masses - eV in pulsar timing arrays, taking into account general polarizati…
Graviton-photon conversion in stochastic magnetic fields
Wataru Chiba, Ryusuke Jinno, Kimihiro Nomura
We study graviton-photon conversion in the presence of stochastic magnetic fields. Assuming Gaussian magnetic fields that may possess nontrivial helicity, and unpolarized gravitati…
