Fermiology in the Weyl semimetals (Nb,Ta)(As,P)

ORAL

Abstract

We present a detailed angular and temperature dependent study of the quantum oscillatory phenomena in the Weyl semimetals, (Ta,Nb)(As,P) under high magnetic fields. In general we find that the P compounds exhibit larger Fermi surfaces with lighter effective masses when compared to the As ones. We show that for (Nb,Ta)As we can reach the quantum limit with the currently available magnetic fields, which seemingly leads to an electronic phase transition.
