Subvolume method for SU(2) Yang-Mills theory at finite temperature: topological charge distributions

Posted by dbos Tokyo

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 […]

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 […]

Analysis of singular subspaces under random perturbations

Posted by dbos Peking

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 […]

On a $mathbb{Z}_3$-valued discrete topological term in 10d heterotic string theories

Posted by dbos Tokyo

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 […]
