Title: Landau quantization in coupled Weyl points: a case study of semimetal NbP

Abstract

Weyl semimetal (WSM) is a newly discovered quantum phase of matter that exhibits topologically protected states characterized by two separated Weyl points with linear dispersion in all directions. Here, via combining theoretical analysis and magneto-infrared spectroscopy of an archetypal Weyl semimetal, niobium phosphide, we demonstrate that the coupling between Weyl points can significantly modify the electronic structure of a WSM and provide a new twist to the protected states. Here, these findings suggest that the coupled Weyl points should be considered as the basis for analysis of realistic WSMs.
