Topological photonics and unidirectional surface plasmon polaritons in a Weyl semimetal

ORAL

Abstract

The axion effect in the dielectric function of Weyl semimetals (WSM) gives rise to topological photonic bands with non-zero Chern number. On the surface of WSM, unidirectional surface plasmon polaritons (SPPs) emerge as a consequence of the topological photonic bands. We found that this SPP can mediate two qubits with decay time much longer than SPP in conventional metals.
