Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Linhao Li, Masahito Yamazaki, Yunqin Zheng, | Summary: We explore non-invertible symmetries in two-dimensional lattice models with subsystem $mathbb Z_2$ symmetry. We introduce a subsystem $mathbb Z_2$-gauging procedure, called the subsystem Kramers-Wannier transformation, which generalizes the ordinary Kramers-Wannier transformation. The corresponding duality operators and defects […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov, , | Summary: Cosmological solitonic objects such as monopoles, cosmic strings, domain walls, oscillons and Q-balls often appear in theories of the early Universe. We demonstrate that such scenarios are generically accompanied by a novel production source of gravitational waves […]

Kavli Affiliate: Jia Liu | First 5 Authors: Leander Thiele, Gabriela A. Marques, Jia Liu, Masato Shirasaki, | Summary: We utilize the probability distribution function (PDF) of normalized convergence maps reconstructed from the Subaru Hyper Suprime-Cam (HSC) Y1 shear catalogue, in combination with the power spectrum, to measure the matter clustering amplitude $S_8=sigma_8sqrt{Omega_m/0.3}$. The large-scale […]
