Recently, a type-II Weyl fermion was theoretically predicted to appear at the contact of
electron and hole Fermi surface pockets. A distinguishing feature of the surfaces of type-II …

A kind of topological material, the type-II Weyl semimetal, was proposed recently where the
Weyl points emerge at the contact points of the electron and hole pockets, resulting in a …

In metallic condensed matter systems two different types of Weyl fermions can in principle
emerge, with either a vanishing (type-I) or with a finite (type-II) density of states at the Weyl …

We report angle-resolved photoemission experiments resolving the distinct electronic
structure of the inequivalent top and bottom (001) surfaces of WT e 2. On both surfaces, we …

It has recently been proposed that electronic band structures in crystals can give rise to a
previously overlooked type of Weyl fermion, which violates Lorentz invariance and …

We use ultrahigh resolution, tunable, vacuum ultraviolet laser angle-resolved photoemission
spectroscopy (ARPES) to study the electronic properties of WTe 2, a material that was …

Weyl semimetal is a new quantum state of matter,,,,,,,,,,, hosting the condensed matter
physics counterpart of the relativistic Weyl fermions originally introduced in high-energy …

The progress in exploiting new electronic materials has been a major driving force in solid-
state physics. As a new state of matter, a Weyl semimetal (WSM), in particular a type-II WSM …

Weyl semimetals are a new member of the topological materials family, featuring a pair of
singly degenerate Weyl cones with linear dispersion around the nodes in the bulk, and …

The recent discovery of a Weyl semimetal in TaAs offers the first Weyl fermion observed in
nature and dramatically broadens the classification of topological phases. However, in TaAs …
