Observation of topological switch between Weyl semimetal and third-order topological insulator phases
Yu-Hong Han, Yi Li, Feng Mei +2
Weyl semimetals and higher-order topological insulators represent two fundamental yet distinct classes of topological matter. While both have been extensively studied in classical-…

Maximal coin-position entanglement and non-Hermitian skin effect in discrete-time quantum walks
Ding Cheng, Yi Li, Hao Zhao +6
A distinctive feature of non-Hermitian systems is the skin effect, which has attracted widespread attention in recent studies. Quantum walks provide a powerful platform for explori…

Observation of higher-order time-dislocation topological modes
Jia-Hui Zhang, Feng Mei, Yi Li +4
Topological dislocation modes resulting from the interplay between spatial dislocations and momentum-space topology have recently attracted significant interest. Here, we theoretic…
