Non-Local and Non-Markovian Effects of a Microscopic Two-Level Defect in Superconducting Quantum Circuits

Yang Gao, Yujia Zhang, Huikai Xu +12

Microscopic two-level systems (TLS) -- ubiquitous atomic-scale defects in solid-state quantum devices -- are a dominant source of qubit decoherence, yet their role is often conside…

Symmetry-protected four double-Weyl fermions and their topological phase transitions in nonmagnetic crystals

Yun-Yun Bai, Ke-Xin Pang, Yan Gao

Realizing Weyl semimetals (WSMs) with the minimal number of Weyl points (WPs) fundamentally simplifies extracting intrinsic topological responses. While a minimum of four conventio…
