Quantifying quasiparticle chirality in a chiral topological semimetal
Jiaju Wang, Jaime Sánchez-Barriga, Amit Kumar +17
Recently, the projection of the electron's spin on its crystal momentum has been proposed as a metric to quantify electronic chirality of Bloch states in crystals, which is expecte…
Suppression of Spectral Gap and Flat Bands on a Cuprate Superconductor Side-Surface
Gabriele Domaine, Mihir Date, Sydney K. Y. Dufresne +27
Side surfaces of cuprate superconductors are expected to display a suppressed -wave order parameter and zero-energy topological flat bands with a large density of states, making…
Evidence of a two-dimensional nitrogen crystalline structure on silver surfaces
Xuegao Hu, Haijun Cao, Zhicheng Gao +11
Nitrogen, the most abundant element in Earth's atmosphere, exists as a diatomic gas under standard temperature and pressure. In the two-dimensional (2D) limit, atomically thin nitr…
1D flat bands in phosphorene nanoribbons with pentagonal nature
Shuo Sun, Jing-Yang You, Zhihao Cai +16
Materials with flat bands can serve as a promising platform to investigate strongly interacting phenomena. However, experimental realization of ideal flat bands is mostly limited t…
