Stability of Axion Dark Matter-Photon Conversion
Emi Masaki, Arata Aoki, Jiro Soda
It is known that a coherently oscillating axion field is a candidate of the dark matter. In the presence of the oscillating axion, the photon can be resonantly produced through the…
Nonlinear resonant oscillation of gravitational potential induced by ultralight axion in gravity
Arata Aoki, Jiro Soda
We study the ultralight axion dark matter with mass around eV in gravity which might resolve the dark energy problem. In particular, we focus on the fact that the…
Photon-Axion Conversion, Magnetic Field Configuration, and Polarization of Photons
Emi Masaki, Arata Aoki, Jiro Soda
We study the evolution of photon polarization during the photon-axion conversion process with focusing on the magnetic field configuration dependence. Most previous studies have be…
Detecting ultralight axion dark matter wind with laser interferometers
Arata Aoki, Jiro Soda
The ultralight axion with mass around eV is known as a candidate of dark matter. A peculiar feature of the ultralight axion is oscillating pressure in time, which produc…
Rational first integrals of geodesic equations and generalised hidden symmetries
Arata Aoki, Tsuyoshi Houri, Kentaro Tomoda
We discuss novel generalisations of Killing tensors, which are introduced by considering rational first integrals of geodesic equations. We introduce the notion of inconstructible…
Pulsar timing signal from ultralight axion in theory
Arata Aoki, Jiro Soda
An ultralight axion around eV is known as a viable dark matter candidate. A distinguished feature of such a dark matter is the oscillating pressure which produces the os…
