Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yotaro Sato, Yuji Tachikawa, Taizan Watari, , | Summary: We argue that having an odd number of Majorana fermion zero modes on a dynamical point-like soliton signifies an inconsistency in a theory with 3+1 and higher dimensions. We check this statement in a couple of examples in […]
Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Daiki Tanabe, Masaya Hasegawa, Masashi Hazumi, Nobuhiko Katayama, Shuhei Kikuchi | Summary: We present a precise thermometry system to monitor room-temperature components of a telescope for radio-astronomy such as cosmic microwave background (CMB) observation. The system realizes precision of 1 mK${rm sqrt{s}}$ on a timescale of 20 […]

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Takeo Minamikawa, Reiko Sakaguchi, Yoshinori Harada, Hideharu Hase, Yasuo Mori | Summary: We demonstrated remote plasmonic enhancement (RPE) by a dense random array of Ag nanoislands (AgNIs) that were partially gold-alloyed and attached with column-structured silica (CSS) overlayer of more than 100 nm in thickness. The physical […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Ryuichi Takahashi, Takahiro Nishimichi, Masahiro Takada, | Summary: The spatial curvature ($Omega_K$) of the Universe is one of the most fundamental quantities that could give a link to the early universe physics. In this paper we develop an approximate method to compute the nonlinear matter […]

Kavli Affiliate: Taizan Watari | First 5 Authors: Abhiram Kidambi, Masaki Okada, Taizan Watari, , | Summary: The study of rational conformal field theories is of particular interest in the moduli space of conformal field theories since such rational points correspond to points in moduli space where the algebraic and arithmetic structure are usually richer, […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Tobias Binder, Sreemanti Chakraborti, Shigeki Matsumoto, Yu Watanabe, | Summary: We study a minimal model for a light scalar dark matter, requiring a light scalar mediator to address the core-cusp problem and interact with the standard model particles. We analyze the model comprehensively by focusing on the […]

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Kai Murai, , | Summary: We study a primordial black hole (PBH) formation scenario based on the Affleck-Dine (AD) mechanism and investigate two PBH mass regions: $M sim 30 M_odot$ motivated by the LIGO-Virgo observations of the binary black hole mergers and $M […]
