Scanning Tunneling Microscopic investigation of a type-II Weyl semimetal surface

ORAL

Abstract

Recent discovery of type-I Weyl fermions has generated a flurry of new research directions in topological materials. The crystal symmetry and spin-orbit-coupling induced tilting of the Weyl cone can lead to strong violation (type-II) of Lorentz invariance in a condensed matter system. In this talk, we will present the atomic resolution scanning tunneling spectro-microscopic investigation on a single-crystalline type-II Weyl semimetal Mo$_{\mathrm{x}}$W$_{\mathrm{1x}}$Te$_{\mathrm{2}}$ for the first time. Interesting type-II Weyl Fermion and topological Fermi arc related physics will be discussed
