In a type I Dirac or Weyl semimetal, the low-energy states are squeezed to a single point in momentum space when the chemical potential μ is tuned precisely to the Dirac/Weyl point. Recently, a type II Weyl semimetal was predicted to exist, where the Weyl states connect hole and electron bands, separated by an indirect gap. This leads to unusual energy states, where hole and electron pockets touch at the Weyl point. Here we present the discovery of a type II topological Weyl semimetal state in…

Evidence for topological type-II Weyl semimetal WTe2
TLDR
Exotic transport properties of type-II Weyl semimetals have been predicted but are yet to be experimentally evidenced and evidences of an anisotropy of negative magnetoresistance and a quantum oscillation arising from the predicted Weyl orbit in the type- II WeylSemimetal WTe2 are reported.
Signature of type-II Weyl semimetal phase in MoTe2
TLDR
This work directly visualize the electronic structure of MoTe2, a recently proposed type-II TWS, using angle-resolved photoemission spectroscopy (ARPES), and unravels the unique surface Fermi arcs, in good agreement with ab initio calculations that have nontrivial topological nature.
Searching for topological Fermi arcs via quasiparticle interference on a type-II Weyl semimetal MoTe2
Weyl semimetals display a novel topological phase of matter where the Weyl nodes emerge in pairs of opposite chirality and can be seen as either a source or a sink of Berry curvature. The exotic
Observation of Weyl Nodes in Robust Type-II Weyl Semimetal WP_{2}.
TLDR
The results ascertain that, due to the spin-orbit coupling, the Weyl nodes originate from the splitting of fourfold degenerate band-crossing points with Chern numbers C=±2 induced by the crystal symmetries of WP_{2}, which is unique among all the discovered WSMs.

Topological surface Fermi arcs in the magnetic Weyl semimetal Co3Sn2S2

Visualizing Type-II Weyl Points in Tungsten Ditelluride by Quasiparticle Interference.
TLDR
Experimental proof that WTe2 is a type-II WSM is presented, and energy-dependent quasiparticle interference patterns are measured with a cryogenic scanning tunneling microscope, revealing the position of the Weyl point and its connection with the Fermi arc surface states, in agreement with prior theoretical predictions.

Type-II Weyl semimetals
TLDR
This work proposes the existence of a previously overlooked type of Weyl fermion that emerges at the boundary between electron and hole pockets in a new phase of matter and discovers a type-II Weyl point, which is still a protected crossing, but appears at the contact of electron and Hole pockets in type- II Weyl semimetals.
