Magnetoresistance in many samples of Dirac semimetals and topological insulators displays nonmonotonic behavior over a wide range of magnetic fields. Here a formula of magnetoconductivity is presented for massless and massive Dirac fermions in Dirac materials due to quantum interference of Dirac fermions in scalar impurity scattering potentials. It reveals a striking crossover from positive to negative magnetoresistivity, uncovering strong competition between weak localization and weak…

Quantum magnetotransport in massive Dirac materials
Massive Dirac fermions break the chiral symmetry explicitly and also make the Berry curvature of the band structure non-Abelian. By utilizing the Green's function technique, we develop a microscopic…

TLDR
It is shown that weak anti-localization (WAL) arises in SOC lattices, although its mechanism and properties are different from the conventional WAL in normal metals with SOC impurities.
Electron-electron interactions and weak antilocalization in few-layer ZrTe5 devices
Much effort has been devoted to the electronic properties of relatively thick ZrTe5 crystals, focusing on their three-dimensional topological effects. Thin ZrTe5 crystals, on the other hand, were…

Possible manifestations of the chiral anomaly and evidence for a magnetic field induced topological phase transition in the type-I Weyl semimetal TaAs
We evaluate the topological character of TaAs through a detailed study of the angular, magnetic-field and temperature dependence of its magnetoresistivity and Hall-effect(s), and of its bulk…
Quantized Fermi arc mediated transport in Weyl semimetal nanowires
We study longitudinal transport in Weyl semimetal nanowires, both in the absence and in the presence of a magnetic flux threading the nanowires. We identify two qualitatively different regimes of t…

Thin films of topological insulator (TI) Bi2Se3 were grown onto the surfaces of FeSe2 layers of different thicknesses on Si (100) substrates by magnetron sputtering, forming bilayer films with smoo...
Anomalous Temperature Dependence of Quantum Correction to the Conductivity of Magnetic Topological Insulators.
TLDR
It is demonstrated that the tiny mass of the surface electrons induced by the bulk magnetization leads to a temperature-dependent correction to the π Berry phase and generates a decoherence mechanism to the phase coherence length of thesurface electrons so that the quantum correction to conductivity can exhibit nonmonotonic behavior by decreasing the temperature.

A conductivity formula for massless and massive Dirac fermions as a function of magnetic field and temperature is presented, by taking into account the electron-electron interaction and quantum interference simultaneously.

It is shown that in a certain range of parameters such a phenomenon can also exist in conventional centrosymmetric and time-reversal invariant conductors, lacking topological protection of the electron spectrum and the chiral anomaly.

Landau quantization and quasiparticle interference in the three-dimensional Dirac semimetal Cd₃As₂.
TLDR
Scanning tunnelling microscopy measurements at sub-kelvin temperatures and high magnetic fields on the II-V semiconductor Cd3As2.2 show that defects mostly influence the valence band, consistent with the observation of ultrahigh-mobility carriers in the conduction band.

TLDR
Applying magnetic fields near the topological phase transition from a topological insulator to a band insulator in Bi1-xSbx the authors observe not only the weak antilocalization phenomenon in magnetoconductivity near zero magnetic fields, but also its upturn above 0.4 T only for E//B.
