Electronic structure of the candidate Weyl phase in MoTe2

ORAL

Abstract

Orthorhombic MoTe2 has been proposed to be a type II Weyl semimetal. This classification is supported by the observation of rare topological phenomena such as Fermi arcs and Weyl nodes through ARPES measurements. A first-order structural transition from the centrosymmetric monoclinic phase at room temperature to the orthorhombic phase, without inversion symmetry, was found through both magnetoresistance and neutron scattering measurements. I will discuss quantum oscillations measurements and their ramifications for the electronic band structure, and how this relates to the topological state and corresponding novel quantum phenomena
