Weyl and Dirac semimetals in three-dimensional solids
TL;DR: Weyl and Dirac semimetals as discussed by the authors are three-dimensional phases of matter with gapless electronic excitations that are protected by topology and symmetry, and they have generated much recent interest.

Hui Li,Hongtao He,Hai-Zhou Lu,Huachen Zhang,Hongchao Liu,Rong Ma,Zhiyong Fan,Shun-Qing Shen,Jiannong Wang +8 more
TL;DR: The observation of NMR in Cd3As2 microribbons in parallel magnetic fields up to 66% at 50 K and visible at room temperatures is reported, demonstrating the chiral anomaly, a long-sought high-energy-physics effect, in solid-state systems.

Two-dimensional Transport Induced Linear Magneto-Resistance in Topological Insulator Bi$_2$Se$_3$ Nanoribbons
TL;DR: It is shown that the linear MR of Bi(2)Se(3) nanoribbons persists to room temperature, underscoring the potential of exploiting topological insulator nanomaterials for room-temperature magneto-electronic applications.

Classical and quantum routes to linear magnetoresistance.
Jingshi Hu,T. F. Rosenbaum +1 more
TL;DR: In this article, it was shown that adding a few parts per million of the proper chemical impurities to indium antimonide, a well-known semiconductor, or redesigning the material's structure on the micrometre scale, can transform its response to an applied magnetic field.

Large magnetoresistance in non-magnetic silver chalcogenides
R. Xu,R. Xu,A. Husmann,Thomas Rosenbaum,Marie-Louise Saboungi,J. E. Enderby,Peter B. Littlewood +6 more
TL;DR: In this paper, the authors describe a novel class of magnetoresistive compounds, the silver chalcogenides, and show that slightly altering the stoichiometry can lead to a marked increase in the magnetic response.

Enhanced Room-Temperature Geometric Magnetoresistance in Inhomogeneous Narrow-Gap Semiconductors.
TL;DR: A symmetric van der Pauw disk of homogeneous nonmagnetic indium antimonide with an embedded concentric gold inhomogeneity is found to exhibit room-temperature geometric magnetoresistance as high as 100, 9100, and 750,000 percent at magnetic fields of 0.05, 0.25, and 4.0 teslas.

Effect of Random Inhomogeneities on Electrical and Galvanomagnetic Measurements
TL;DR: In this article, the effects of inhomogeneities on piezoelectric, galvanomagnetic, and thermocyclic measurements have been investigated and formulas for all the effects are derived which are asymptotically exact in the limit of small fractional fluctuations in the local conductivity.

TL;DR: In this paper, the major formulae suggested for the dielectric constant of a mixture of two components (at least one of which has the form of particles containing many molecules) are shown to be all related to another.
