Effective Field Theory of Large Scale Structure in modified gravity and application to Degenerate Higher-Order Scalar-Tensor theories
Shin'ichi Hirano, Tomohiro Fujita
In modified gravity, the one-loop matter power spectrum exhibits an ultraviolet divergence as shown in the framework of the degenerate higher-order scalar-tensor theory. To address…
Stochastic effects on observation of ultralight bosonic dark matter
Hiromasa Nakatsuka, Soichiro Morisaki, Tomohiro Fujita +4
Ultralight bosonic particles are fascinating candidates of dark matter (DM). It behaves as classical waves in our Galaxy due to its large number density. There have been various me…
Universality of linear perturbations in SU()-natural inflation
Tomohiro Fujita, Kai Murai, Ryo Namba
We prove the universality of predictions for linear perturbations from the entire class of models of inflation driven by a pseudo-scalar field coupled to an SU() gauge boson, wh…
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…
Dark matter Axion search with riNg Cavity Experiment DANCE: Development of control system for long-term measurement
Hiroki Fujimoto, Yuka Oshima, Masaki Ando +4
Axion-like particles (ALPs) are pseudo-scalar particles that are candidates for ultralight dark matter. ALPs interact with photons slightly and cause the rotational oscillation of…
Dark matter Axion search with riNg Cavity Experiment DANCE: Current sensitivity
Yuka Oshima, Hiroki Fujimoto, Masaki Ando +5
Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed. To search for axion-like particles, we aim to detect the rotation and oscillation of optical linear polar…
