Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Shunsuke Neda, Satoshi Shirai, | Summary: Recent observations by pulsar timing arrays (PTAs) indicate a potential detection of a stochastic gravitational wave (GW) background. Metastable cosmic strings have been recognized as a possible source of the observed signals. In this paper, we propose […]

Kavli Affiliate: Huawei Zhang | First 5 Authors: Shenglan Sun, Fei Wang, Huawei Zhang, Xiang-Xiang Xue, Yang Huang | Summary: Motivated by the vast gap between photometric and spectroscopic data volumes, there is great potential in using 5D kinematic information to identify and study substructures of the Milky Way. We identify substructures in the Galactic […]
Kavli Affiliate: Jing Wang | First 5 Authors: Huan Wang, Rui Shi, Zhaochen Liu, Jing Wang, | Summary: We construct a minimal lattice model to provide an orbital description of lowest and first Landau levels. With the maximally localized Wannier functions with $s$, $p_-$, $p_+$ orbital characteristics, a three-orbital model is developed, where the lowest […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Joheen Chakraborty, Kevin B. Burdge, Saul A. Rappaport, James Munday, Hai-Liang Chen | Summary: We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This significantly augments the population of mass-transferring binaries at […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Zi-Hang Zhu, Ying Liu, Gianluca Lagnese, Federica Maria Surace, Wei-Yong Zhang | Summary: In the context of quantum electrodynamics, the decay of false vacuum leads to the production of electron-positron pair, a phenomenon known as the Schwinger effect. In practical experimental scenarios, producing a pair requires an […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yuhui Guo, Jian Song, Ran Wang, Yimin Xiao, | Summary: We consider the following stochastic space-time fractional diffusion equation with vanishing initial condition:$$ partial^{beta} u(t, x)=- left(-Deltaright)^{alpha / 2} u(t, x)+ I_{0+}^{gamma}left[dot{W}(t, x)right],quad tin[0,T],: x in mathbb{R}^d,$$ where $alpha>0$, $betain(0,2)$, $gammain[0,1)$, $left(-Deltaright)^{alpha/2}$ is the fractional/power of Laplacian […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Donggeun Tak, Z. Lucas Uhm, Gregory S. H. Paek, Myungshin Im, Makoto Arimoto | Summary: Gamma-ray bursts (GRBs) are the most energetic explosions in the universe, and their afterglow emission provides an opportunity to probe the physics of relativistic shock waves in an extreme environment. Several key […]
