Experimental Discovery of Weyl Semimetal TaAs
Physical Review X, 2015 Weyl semimetals are a class of materials that can be regarded as three-dimensional analogs of graphene upon breaking time-reversal or inversion symmetry.

All‐Electric Spin Device Operation Using the Weyl Semimetal, WTe2, at Room Temperature
Advanced Electronic Materials, 2023 Topological quantum materials (TQMs) possess abundant and attractive spin physics, and a Weyl semimetal is the representative material because of the generation of spin polarization that is available for spin devices due to its Weyl nature.

Negative Refraction in Weyl Semimetals [PDF]
Journal of the Physical Society of Japan, 2017 We theoretically propose that Weyl semimetals may exhibit negative refraction at some frequencies close to the plasmon frequency, allowing transverse magnetic (TM) electromagnetic waves with frequencies smaller than the plasmon frequency to propagate in the Weyl semimetals.

A Raman probe of phonons and electron–phonon interactions in the Weyl semimetal NbIrTe4
Scientific Reports, 2021 There is tremendous interest in measuring the strong electron–phonon interactions seen in topological Weyl semimetals. The semimetal NbIrTe4 has been proposed to be a Type-II Weyl semimetal with 8 pairs of opposite Chirality Weyl nodes which are very ...

TYPE-II WEYL SEMIMETAL VS GRAVASTAR [PDF]
ПИСЬМА В ЖУРНАЛ ЭКСПЕРИМЕНТАЛЬНОЙ И ТЕОРЕТИЧЕСКОЙ ФИЗИКИ, 2021 The boundary between the type I and type II Weyl semimetals serves as the event horizon for the "relativistic" fermions. The interior of the black hole is represented by the type II Weyl semimetal, where the Fermi surface is formed. The process of the filling of the Fermi surface by electrons results in the relaxation inside the horizon.

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).

Linear magnetoconductivity in an intrinsic topological Weyl semimetal
New Journal of Physics, 2016 Searching for the signature of the violation of chiral charge conservation in solids has inspired a growing passion for the magneto-transport in topological semimetals.

From Nodal Chain Semimetal to Weyl Semimetal in HfC [PDF]
Physical Review Letters, 2017 Based on first-principles calculations and effective model analysis, we propose that the WC-type HfC, in the absence of spin-orbit coupling (SOC), can host a three-dimensional nodal chain semimetal state. Distinguished from the previous material IrF4 [T.

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.
