Emergence of Chern metal in a moiré Kondo lattice
Wenjin Zhao, Zui Tao, Yichi Zhang +9
A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. It can emerge as a doped Chern insulator, but theoretical studies have also predicted its e…

Edge Channels of Broken-Symmetry Quantum Hall States in Graphene probed by Atomic Force Microscopy
Sungmin Kim, Johannes Schwenk, Daniel Walkup +12
The quantum Hall (QH) effect, a topologically non-trivial quantum phase, expanded and brought into focus the concept of topological order in physics. The topologically protected qu…
