but act as an insulator inside. Called organic topological insulators, these materials are made from a thin molecular sheet (left) that resembles chicken wire and conducts electricity on its right ...

Experiment has now proved the existence of the predicted three-dimensional 'topological insulator' in the semiconducting alloy Bi 1−x Sb x. One of the triumphs of quantum mechanics in the ...

An intrinsic magnetic topological insulator with gapped surface states would be very useful for both fundamental and application prospects. Now, the use of the time-periodic drive of a laser makes ...
