Kavli Affiliate: Jia Liu | First 5 Authors: Zhuqing Liu, Xin Zhang, Jia Liu, , | Summary: To increase the training speed of distributed learning, recent years have witnessed a significant amount of interest in developing both synchronous and asynchronous distributed stochastic variance-reduced optimization methods. However, all existing synchronous and asynchronous distributed training algorithms suffer […]

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Yonit Hochberg, Eric Kuflik, Kevin Langhoff | Summary: We introduce Super-Resonant Dark Matter, a model of self-interacting dark matter based on the low energy effective theory of supersymmetric QCD. The structure of the theory ensures a resonant enhancement of the self-interactions of the […]

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Carolyn Kierans, Tadayuki Takahashi, Gottfried Kanbach, , | Summary: Compton telescopes rely on the dominant interaction mechanism in the MeV gamma-ray energy range: Compton scattering. By precisely recording the position and energy of multiple Compton scatter interactions in a detector volume, a photon’s original direction and energy […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ying-Hsuan Lin, Masaki Okada, Sahand Seifnashri, Yuji Tachikawa, | Summary: It is known that the asymptotic density of states of a 2d CFT in an irreducible representation $rho$ of a finite symmetry group $G$ is proportional to $(dimrho)^2$. We show how this statement can be generalized when […]

Kavli Affiliate: Masahiro Takada | First 5 Authors: Carolina Cuesta-Lazaro, Takahiro Nishimichi, Yosuke Kobayashi, Cheng-Zong Ruan, Alexander Eggemeier | Summary: In this series of papers, we present a simulation-based model for the non-linear clustering of galaxies based on separate modelling of clustering in real space and velocity statistics. In the first paper, we present an […]

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Frank J. Qu, Blake D. Sherwin, Omar Darwish, Toshiya Namikawa, Mathew S. Madhavacheril | Summary: CMB lensing maps probe the mass distribution in projection out to high redshifts, but significant sensitivity to low-redshift structure remains. In this paper we discuss a method to remove the low-redshift contributions […]

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Thuong D. Hoang, Tomotake Matsumura, Ryota Takaku, Takashi Hasebe, Tommaso Ghigna | Summary: LiteBIRD is the Cosmic Microwave Background (CMB) radiation polarization satellite mission led by ISAS/JAXA. The main scientific goal is to search for primordial gravitational wave signals generated from the inflation epoch of the Universe. […]

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Tommaso Ghigna, Tomotake Matsumura, Yuki Sakurai, Ryota Takaku, Kunimoto Komatsu | Summary: Most upcoming CMB experiments are planning to deploy between a few thousand and a few hundred thousand TES bolometers in order to drastically increase sensitivity and unveil the B-mode signal. Differential systematic effects and $1/f$ […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Takahiko Matsubara, Misao Sasaki, , , | Summary: We perturbatively study the effect of non-Gaussianities on the mass fraction of primordial black holes (PBHs) at the time of formation by systematically taking its effect into account in the one-point probability distribution function of the primordial curvature perturbation. […]
