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.

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.

Electric quantum oscillations in Weyl semimetals [PDF]

Physical Review Research, 2021
Electronic transport in Weyl semimetals is quite extraordinary due to the topological property of the chiral anomaly generating the charge pumping between two distant Weyl nodes with opposite chiralities under parallel electric and magnetic fields. Here, we develop a full nonequilibrium quantum transport theory of the chiral anomaly, based on the fact ...

Weyl Semimetals as Hydrogen Evolution Catalysts [PDF]

Advanced Materials, 2017
The search for highly efficient and low‐cost catalysts is one of the main driving forces in catalytic chemistry. Current strategies for the catalyst design focus on increasing the number and activity of local catalytic sites, such as the edge sites of molybdenum disulfides in the hydrogen evolution reaction (HER).

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.

Visualizing discrete Fermi surfaces and possible nodal-line to Weyl state evolution in ZrSiTe

npj Quantum Materials, 2022
Topological nodal line semimetals (TNLSMs) represent a quantum state of topological matter. When the crystal/time-reversal symmetry is broken, a nodal line state is expected to evolve into a Dirac semimetal, a Weyl semimetal, or other topological phases ...
