Sketch of planar Hall effect (PHE) in topological Weyl semimetals with magnetic and electric fields aligned in the same direction. In this case, the trace of the PHE conductivity Tr[X] is in direct ...
Heterostructures consisting of magnetic insulator layers (e.g., EuS, YIG) and topological insulator films have also been explored for realizing QAH insulators. The proximity-induced magnetic exchange ...
Quantized conductance — whereby the current through a wire changes in a stepwise, rather than continuous manner — has been seen in very narrow ribbons of graphene for the first time. The discovery was ...
Detecting topological order in cold-atom experiments is an ongoing challenge, the resolution of which offers novel perspectives on topological matter. In material systems, unambiguous signatures of ...
