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 ...

PASADENA, Calif.—Computers, light bulbs, and even people generate heat—energy that ends up being wasted. With a thermoelectric device, which converts heat to electricity and vice versa, you can ...
