The study of charge-density wave (CDW) distortions in Weyl semimetals has recently returned to the forefront, inspired by experimental interest in materials such as (TaSe4)2I. However, the interplay between collective phonon excitations and charge transport in Weyl-CDW systems has not been systematically studied. In this paper, we examine the longitudinal electromagnetic response due to collective modes in a Weyl semimetal gapped by a quasi-one-dimensional charge-density wave order, using both… 


Axionic charge-density wave in the Weyl semimetal (TaSe4)2I
The results show that it is possible to find experimental evidence for axions in strongly correlated topological condensed matter systems, which have so far been elusive in any other context.
A charge-density-wave topological semimetal
Topological physics and strong electron–electron correlations in quantum materials are typically studied independently. However, there have been rapid recent developments in quantum materials in
Dynamics of charge density wave order in the quasi one dimensional conductor (TaSe4)2I probed by femtosecond optical spectroscopy
Carrier and collective mode dynamics in the quasi one-dimensional charge density wave (CDW) system (TaSe4)2I have been investigated by means of time-resolved optical pump-probe spectroscopy. In the
Axionic band topology in inversion-symmetric Weyl-charge-density waves
In recent theoretical and experimental investigations, researchers have linked the low-energy field theory of a Weyl semimetal gapped with a charge-density wave (CDW) to high-energy theories with
Helicity-dependent photocurrents in the chiral Weyl semimetal RhSi
Measurements of CPGE in the chiral Weyl semimetal RhSi are reported, revealing a C PGE response in an energy window that closes at 0.65 eV, in agreement with the predictions of density functional theory.
Band Engineering of Dirac Semimetals Using Charge Density Waves
A new mechanism is introduced, which is based on charge density waves and non-symmorphic symmetry, to design an idealized Dirac semimetal, and it is shown experimentally that the antiferromagnetic compound GdSb0.46 Te1.48 is a nearly ideal DiracSemimetal based on the proposed mechanism, meaning that most interfering bands at the Fermi level are suppressed.
Giant anisotropic nonlinear optical response in transition metal monopnictide Weyl semimetals
An optical second-harmonic generation study of a series of transition metal monopnictide Weyl semimetals reveals a giant, anisotropic nonlinear optical response in these systems. Although Weyl
Quantized circular photogalvanic effect in Weyl semimetals
In a class of Weyl semimetals and three-dimensional Rashba materials without inversion and mirror symmetries, the injection contribution to the CPGE trace is effectively quantized in terms of the fundamental constants e, h, c and with no material-dependent parameters.
The chiral anomaly and thermopower of Weyl fermions in the half-Heusler GdPtBi.
A large negative LMR with the field-steering properties specific to the chiral anomaly is observed in the half-Heusler GdPtBi, and the scheme of creating Weyl nodes from quadratic bands suggests that the Chiral anomaly may be observable in a broad class of semimetals.
Observation of Weyl nodes in TaAs
Experiments show that TaAs is a three-dimensional topological Weyl semimetal. In 1929, H. Weyl proposed that the massless solution of the Dirac equation represents a pair of a new type of particles,
