The surface states of a topological insulator in a fine-tuned magnetic field are ideal candidates for realizing a topological metal which is protected against disorder. Its signatures are (i) a conductance plateau in long wires in a finely tuned longitudinal magnetic field and (ii) a conductivity wh...
