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 ...

Negative magnetoresistance without well-defined chirality in the Weyl semimetal TaP

Nature Communications, 2016
Magnetoresistance of topological semimetal shows unusual electron transport behaviour. Here, Arnold et al. demonstrate detailed Fermi surface topology of Weyl semimetal TaP and show that negative longitudinal magnetoresistance shows up without well ...

Semimetal with both Rarita-Schwinger-Weyl and Weyl excitations

, 2016
A relativistic spinor with spin 3/2 is historically called a Rarita-Schwinger spinor. The right-and left-handed chiral degrees of freedom for the massless Rarita-Schwinger spinor are independent and are thought of as the left and right Weyl fermions with

New type of Weyl semimetal with quadratic double Weyl fermions

, 2016
Weyl semimetals have attracted worldwide attention due to their wide range of exotic properties predicted in theories. The experimental realization had remained elusive for a long time despite much effort. Very recently, the first Weyl semimetal has been

Real higher-order Weyl photonic crystal

Nature Communications, 2023
Higher-order Weyl semimetals are a family of recently predicted topological phases simultaneously showcasing unconventional properties derived from Weyl points, such as chiral anomaly, and multidimensional topological phenomena originating from higher ...

A strongly robust type II Weyl fermion semimetal state in Ta3S2 [PDF]

, 2016
Weyl semimetals are of great interest because they provide the first realization of the Weyl fermion, exhibit exotic quantum anomalies, and host Fermi arc surface states.

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

Advanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Zitterbewegung in time-reversal Weyl semimetals [PDF]

Journal of Physics: Condensed Matter, 2018
Abstract We perform a systematic study of the Zitterbewegung effect of fermions, which are described by a Gaussian wave with broken spatial-inversion symmetry in a three-dimensional low-energy Weyl semimetal. Our results show that the motion of fermions near the Weyl points is characterized by rectilinear motion and Zitterbewegung ...
