Ultralight dark matter searches with KAGRA gravitational wave telescope
Yuta Michimura, Tomohiro Fujita, Jun'ya Kume +5
Among various dark matter candidates, bosonic ultralight fields with masses below 1~eV are well motivated. Recently, a number of novel approaches have been put forward to search fo…
First observation and analysis of DANCE: Dark matter Axion search with riNg Cavity Experiment
Yuka Oshima, Hiroki Fujimoto, Masaki Ando +9
Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed to search for axion dark matter [Phys. Rev. Lett. 121, 161301 (2018)]. We aim to detect the rotation and o…
Dark matter Axion search with riNg Cavity Experiment DANCE: Design and development of auxiliary cavity for simultaneous resonance of linear polarizations
Hiroki Fujimoto, Yuka Oshima, Masaki Ando +4
Axion-like particles (ALPs) are undiscovered pseudo-scalar particles that are candidates for ultralight dark matter. ALPs interact with photons slightly and cause the rotational os…
SU()-natural inflation
Tomohiro Fujita, Kyohei Mukaida, Kai Murai +1
We study SU() gauge fields that couple to the inflaton through the Chern-Simons term. We provide a general procedure to construct homogeneous, isotropic, and attractor solutions…
Gravitational wave trispectrum in the axion-SU(2) model
Tomohiro Fujita, Kai Murai, Ippei Obata +1
We study the trispectrum of the gravitational waves (GWs) generated through the dynamics of an axionic spectator field and SU(2) gauge fields during inflation. In non-Abelian gauge…
Axion dark matter search using arm cavity transmitted beams of gravitational wave detectors
Koji Nagano, Hiromasa Nakatsuka, Soichiro Morisaki +3
Axion is a promising candidate for ultralight dark matter which may cause a polarization rotation of laser light. Recently, a new idea of probing the axion dark matter by optical l…
