Kavli Affiliate: Ran Wang | First 5 Authors: Fuchun Ge, Ran Wang, Chen Qu, Peikun Zheng, Apurba Nandi | Summary: Machine learning potentials (MLPs) are widely applied as an efficient alternative way to represent potential energy surfaces (PES) in many chemical simulations. The MLPs are often evaluated with the root-mean-square errors on the test set […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Norikazu Yamada, Masahito Yamazaki, Ryuichiro Kitano, , | Summary: We apply the previously-developed sub-volume method to study the $theta$-dependence of the four-dimensional SU(2) Yang-Mills theory. We calculate the first two coefficients, the topological susceptibility $chi$ and the fourth cumulant $b_2$, in the $theta$-expansion of the free energy […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Norikazu Yamada, Masahito Yamazaki, Ryuichiro Kitano, , | Summary: We apply the previously-developed sub-volume method to study the $theta$-dependence of the four-dimensional SU(2) Yang-Mills theory at finite temperature. We calculate the first two coefficients, the topological susceptibility $chi$ and the fourth cumulant $b_2$, in the $theta$-expansion of […]
Kavli Affiliate: Li Xin Li | First 5 Authors: The LHAASO Collaboration, Zhen Cao, F. Aharonian, Q. An, A. Axikegu | Summary: We present the measurements of all-particle energy spectrum and mean logarithmic mass of cosmic rays in the energy range of 0.3-30 PeV using data collected from LHAASO-KM2A between September 2021 and December 2022, […]
Xiaolong Du, Andrew Benson, Zhichao Carton Zeng, Tommaso Treu, Annika H. G. Peter | Summary: [[{“value”:”The internal structure and abundance of dark matter halos and subhalos are powerful probes of the nature of dark matter. In order to compare observations with dark matter models, accurate theoretical predictions of these quantities are needed. We present a […]

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We present a comprehensive analysis of singular vector and singular subspace perturbations in the context of the signal plus random Gaussian noise matrix model. Assuming a low-rank signal matrix, we extend the Wedin-Davis-Kahan theorem in a fully generalized manner, applicable […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Hao Y. Zhang, , , | Summary: We show that the low-energy effective actions of two ten-dimensional supersymmetric heterotic strings are different by a $mathbb{Z}_3$-valued discrete topological term even after we turn off the $E_8times E_8$ and $Spin(32)/mathbb{Z}_2$ gauge fields. This will be demonstrated by […]

Kavli Affiliate: Xian Chen | First 5 Authors: Han Yan, Xian Chen, Jinhai Zhang, Fan Zhang, Mengyao Wang | Summary: The recent increasing interest in detecting gravitational waves (GWs) by lunar seismic measurement urges us to have a clear understanding of the response of the moon to passing GWs. In this paper, we clarify the […]
