Non-Hermitian second-order topological insulator with point gap
Xue-Min Yang, Hao Lin, Jian Li +3
The zero-mode corner states in the gap of two-dimensional non-Hermitian Su-Schrieffer-Heeger model are robust to infinitesimal perturbations that preserve chiral symmetry. However,…
Unraveling Intertwined Orders in the Strongly Correlated Kagome Metal CsCr3Sb5
Liangyang Liu, Yidian Li, Hengxin Tan +11
While correlated phenomena of flat bands have been extensively studied in twisted systems, the ordered states that emerge from interactions in the intrinsic flat bands of kagome la…
Discovery of terahertz-frequency orbitally-coupled magnons in a kagome ferromagnet
Mengqian Che, Weizhao Chen, Maoyuan Wang +12
In ferromagnetic materials, magnons - quanta of spin waves - typically resonate in the gigahertz range. Beyond conventional magnons, while theoretical studies have predicted magnon…
Ultrafast Dynamics of Bilayer and Trilayer Nickelate Superconductors
Y. D. Li, Y. T. Cao, L. Y. Liu +16
In addition to the pressurized high-temperature superconductivity, bilayer and trilayer nickelate superconductors Lan+1NinO3n+1 (n = 2 and 3) exhibit many intriguing properties at…
