Evidence of large-scale and room-temperature stair-stepped quantum spin Hall states in Bi4Br4

Topological insulators host exotic quantum phenomena such as the quantum spin Hall (QSH) effect, which enables dissipationless one-dimensional edge conduction. Realizing such states at room temperature and on a macroscopic scale is essential for energy-efficient electronics and quantum technologies, yet remains a fun...

Observation of Kondo Effect in Rhombohedral Graphene Superlattices

Kondo effect in strongly correlated systems arises from the antiferromagnetic coupling between itinerant conduction electrons and localized magnetic moments, giving rise to a variety of exotic quantum phenomena. Two-dimensional moir\'e superlattice systems provide a highly tunable platform featuring topological flat ba...
