Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Xiangchong Li, Masahiro Takada, Takahiro Nishimichi, Satoshi Tanaka | Summary: The baryonic feedback effect is considered as a possible solution to the so-called $S_8$ tension indicated in cosmic shear cosmology. The baryonic effect is more significant on smaller scales, and affects the cosmic shear two-point […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Masaki Okada, Yuji Tachikawa, , , | Summary: Non-invertible symmetries of quantum field theories and many-body systems generalize the concept of symmetries by allowing non-invertible operations in addition to more ordinary invertible ones described by groups. The aim of this paper is to point out that these […]
Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Zifan Zhang, Jia Liu, , | Summary: In actor-critic framework for fully decentralized multi-agent reinforcement learning (MARL), one of the key components is the MARL policy evaluation (PE) problem, where a set of $N$ agents work cooperatively to evaluate the value function of the global […]
Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, , , , | Summary: We found an interesting application of the K-theoretic Heisenberg algebras of Weiqiang Wang to the foundations of permutation equivariant K-theoretic Gromov–Witten theory. We also found an explicit formula for the genus 0 correlators in the permutation equivariant Gromov–Witten theory of […]
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: 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: Tadayuki Takahashi | First 5 Authors: Steven Christe, Lindsay Glesener, Camilo Buitrago-Casas, Shin-Nosuke Ishikawa, Brian Ramsey | Summary: The Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket payload flew for the second time on 2014 December 11. To enable direct Hard X-Ray (HXR) imaging spectroscopy, FOXSI makes use of grazing-incidence replicated focusing optics […]
Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We study a millicharged co-interacting dark matter scenario, where the primary dark matter constituent is the dark photon $A’$ and the secondary component is the fermion $chi$. In this model, $chi$ interacts with $A’$ via a $U(1)’$ […]
