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 ...

Observation of the Chiral-Anomaly-Induced Negative Magnetoresistance in 3D Weyl Semimetal TaAs
Physical Review X, 2015 Weyl semimetal is the three-dimensional analog of graphene. According to quantum field theory, the appearance of Weyl points near the Fermi level will cause novel transport phenomena related to chiral anomaly.

Communications Physics, 2022 Weyl semimetals exhibit a unique feature known as Weyl nodes, which give rise to non-trivial topological features such as an anomalous Hall effect, and there are many efforts to try and control such properties.

Chemistry – A European Journal, EarlyView.Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Mn‐Substituted Topological Phase Transition in Topological Insulator Pt2HgSe3
Advanced Electronic Materials, Volume 12, Issue 19, 12 October 2026.ABSTRACT Topological materials have gained a significant interest in recent years due to their unique features, leading to topological insulators (TI), Dirac or Weyl semimetals, etc. The layered material Pt2HgSe3${\rm Pt}_2{\rm HgSe}_3$ is found to be a dual TI characterized by significant spin–orbit coupling and band inversion.

Anomalous Hall effect in dense QCD matter
Physics Letters B, 2018 In this letter, we investigate the anomalous Hall effect in dense QCD matter. We use here the Nambu–Jona Lasinio model as an effective model of QCD.

Room‐Temperature, Flexible MnBi2Te4/As2Te3 Thin‐Film Heterojunction Array Photodetectors
Advanced Photonics Research, Volume 7, Issue 9, September 2026.This study presents a room‐temperature, flexible MnBi2Te4/As2Te3 thin‐film heterojunction array photodetector fabricated via cost‐effective thermal evaporation. The device exhibits a broadband photoresponse from 450 to 1550 nm, with an ultrafast response time of less than 80 μs, a maximum responsivity (Ri) of 47.5 mA W−1, and a specific detectivity (D*)

Anomalous Hall Conductivity and Nernst Effect of the Ideal Weyl Semimetallic Ferromagnet EuCd2As2
Advanced Science, 2023 Weyl semimetal is a unique topological phase with topologically protected band crossings in the bulk and robust surface states called Fermi arcs. Weyl nodes always appear in pairs with opposite chiralities, and they need to have either time‐reversal or ...
