Realization of a two-dimensional Weyl semimetal and topological Fermi strings [PDF]

Nature Communications
A two-dimensional (2D) Weyl semimetal, akin to a spinful variant of graphene, represents a topological matter characterized by Weyl fermion-like quasiparticles in low dimensions.

Fermi Arcs and Their Topological Character in the Candidate Type-II Weyl Semimetal MoTe_{2}

Physical Review X, 2016
We report a combined experimental and theoretical study of the candidate type-II Weyl semimetal MoTe_{2}. Using laser-based angle-resolved photoemission, we resolve multiple distinct Fermi arcs on the inequivalent top and bottom (001) surfaces.

Weyl semimetal/insulator transition from holography

Journal of High Energy Physics, 2018
We study a holographic model which exhibits a quantum phase transition from the strongly interacting Weyl semimetal phase to an insulating phase. In the holographic insulating phase there is a hard gap in the real part of frequency dependent diagonal ...

High-pressure induced Weyl semimetal phase in 2D Tellurium

Communications Physics, 2023
Relativistic Weyl fermion quasiparticles in Weyl semimetal bring the electron’s chirality degree of freedom into the electrical transport and give rise to exotic phenomena.

Chiral Landau levels in Weyl semimetal NbAs with multiple topological carriers

Nature Communications, 2018
How the carriers behave in a Weyl semimetal if they occupy the lowest Landau level remains elusive. Here, the authors report evidences of electrons occupying zeroth chiral Landau levels with distinct linear dispersion behaviors for two inequivalent Weyl ...

Stability of the Weyl-semimetal phase on the pyrochlore lattice

New Journal of Physics, 2018
Motivated by the proposal of a Weyl-semimetal phase in pyrochlore iridates, we consider a Hubbard-type model on the pyrochlore lattice. To shed light on the question as to why such a state has not been observed experimentally, its robustness is analyzed.

Signature of type-II Weyl semimetal phase in MoTe2

Nature Communications, 2017
A special class of topological Weyl semimetal state is predicted without respecting Lorentz symmetry. Here, Jianget al. report direct visualization of the unique surface Fermi arcs of MoTe2, confirming its type-II topological Weyl semimetal nature.
