Universal $L^{2}$ -approximation using median digital-net algorithms

Ziyang Ye, Xiaoqun Wang, Zexin Pan

The paper introduces a median digital‑net algorithm that approximates non‑periodic functions on the unit cube in the L2 norm by estimating Walsh coefficients from randomized sample…

Altermagnetic Ground State in Distorted Kagome Metal CsCr $_{3}$ Sb $_{5}$

Chenchao Xu, Siqi Wu, Guo-Xiang Zhi +5

The CsCr $_{3}$ Sb $_{5}$ exhibits superconductivity in close proximity to a density-wave (DW) like ground state at ambient pressure\cite{Liu:2024aa}, however details of the DW is still e…
