Subsystem Non-Invertible Symmetry Operators and Defects

Posted by dbos Tokyo

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 […]

Giant planet engulfment by evolved giant stars: light curves, asteroseismology, and survivability

Posted by dbos UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: Christopher E. O’Connor, Lars Bildsten, Matteo Cantiello, Dong Lai, | Summary: About ten percent of Sun-like ($1$-$2 M_odot$) stars will engulf a $1$-$10 M_{rm J}$ planet as they expand during the red giant branch (RGB) or asymptotic giant branch (AGB) phase of their evolution. Once engulfed, these […]

Optical readout of the chemical potential of two-dimensional electrons

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zhengchao Xia, Yihang Zeng, Bowen Shen, Roei Dery, Kenji Watanabe | Summary: The chemical potential u of an electron system is a fundamental property of a solid. A precise measurement of u plays a crucial role in understanding the electron interaction and quantum states of matter. However, […]

Transverse momentum dependent shape function for $J/ψ$ production in SIDIS

Posted by klaurent Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Daniël Boer, Jelle Bor, Luca Maxia, Cristian Pisano, Feng Yuan | Summary: It has been shown previously that the transverse momentum dependent (TMD) factorization of heavy quarkonium production requires a TMD shape function. Its perturbative tail can be extracted by matching the cross sections valid at low […]
