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 axion dark matter in low-frequency terrestrial electromagnetic fields: formulation and predictions
Atsushi Taruya, Atsushi Nishizawa, Yoshiaki Himemoto
We develop a theoretical framework for axion dark matter (DM) searches using terrestrial electromagnetic (EM) fields, enabling a global and quantitative characterization of the sig…
Axion dark matter search from terrestrial magnetic fields at extremely low frequencies
Atsushi Nishizawa, Atsushi Taruya, Yoshiaki Himemoto
The natural environment of the Earth can act as a sensitive detector for dark matter in ultralight axions. When axions with masses between and $1\times1…
Hunting axion dark matter signatures in low-frequency terrestrial magnetic fields
Atsushi Taruya, Atsushi Nishizawa, Yoshiaki Himemoto
We show that Earth's natural environment can serve as a powerful probe for ultralight axion dark matter. In the presence of global geomagnetic fields, the axions with masses rangin…
After bulky brane inflation
Jun'ichi Yokoyama, Yoshiaki Himemoto
Reheating or entropy production on the three-brane from a decaying bulk scalar field is studied in the brane-world picture of the Universe. It is shown that a significant amount of…
