Weyl and Dirac semimetals in three-dimensional solids

NP Armitage, EJ Mele, A Vishwanath - Reviews of Modern Physics, 2018 - APS
Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Dielectric response and novel electromagnetic modes in three-dimensional Dirac semimetal films

OV Kotov, YE Lozovik - Physical Review B, 2016 - APS
Using the Kubo formalism we have calculated the local dynamic conductivity of a bulk, ie,
three-dimensional (3D), Dirac semimetal (BDS). We obtain that at frequencies lower than …

High-dimensional disorder-driven phenomena in Weyl semimetals, semiconductors, and related systems

SV Syzranov, L Radzihovsky - Annual Review of Condensed …, 2018 - annualreviews.org
It is commonly believed that a noninteracting disordered electronic system can undergo only
the Anderson metal-insulator transition. It has been suggested, however, that a broad class …

Nernst and magnetothermal conductivity in a lattice model of Weyl fermions

G Sharma, P Goswami, S Tewari - Physical Review B, 2016 - APS
Weyl semimetals (WSMs) are topologically protected three-dimensional materials whose
low-energy excitations are linearly dispersing massless Dirac fermions, possessing a …

Inhomogeneous weyl and dirac semimetals: Transport in axial magnetic fields and fermi arc surface states from pseudo-landau levels

AG Grushin, JWF Venderbos, A Vishwanath, R Ilan - Physical Review X, 2016 - APS
Topological Dirac and Weyl semimetals have an energy spectrum that hosts Weyl nodes
appearing in pairs of opposite chirality. Topological stability is ensured when the nodes are …

Giant tunable nonreciprocity of light in Weyl semimetals

OV Kotov, YE Lozovik - Physical Review B, 2018 - APS
The propagation of light in Weyl semimetal films is analyzed. The magnetic family of these
materials is known by anomalous Hall effect, which, being enhanced by the large Berry …

High-field magnetoconductivity of topological semimetals with short-range potential

HZ Lu, SB Zhang, SQ Shen - Physical Review B, 2015 - APS
Weyl semimetals are three-dimensional topological states of matter, in a sense that they host
paired monopoles and antimonopoles of Berry curvature in momentum space, leading to the …

Optical evidence for a Weyl semimetal state in pyrochlore

AB Sushkov, JB Hofmann, GS Jenkins, J Ishikawa… - Physical Review B, 2015 - APS
A Weyl semimetallic state with pairs of nondegenerate Dirac cones in three dimensions was
recently predicted to occur in the antiferromagnetic state of the pyrochlore iridates. Here, we …

Linear magnetochiral transport in tilted type-I and type-II Weyl semimetals

K Das, A Agarwal - Physical Review B, 2019 - APS
Berry curvature in Weyl semimetals leads to intriguing magnetoconductivity and
magnetothermal transport properties. Here, we explore the impact of the tilting of the Weyl …

Surface plasmon polaritons in topological Weyl semimetals

J Hofmann, S Das Sarma - Physical Review B, 2016 - APS
We consider theoretically surface plasmon polaritons in Weyl semimetals. These materials
contain pairs of band touching points—Weyl nodes—with a chiral topological charge, which …
