Weyl semimetals, prototypical three dimensional topological metals, possess a unique band structure that has enriched the ``standard model'' of metallic behavior. This work unveils how the unusual topological surface states of Weyl semimetals radically alter their plasmonic characteristics, yielding intrinsic hyperbolic surface plasmons. These Fermi-arc plasmons have a rich phenomenology, and arise from the coupled dynamics of carriers both on the unusual open-segment surface Fermi arc and the… 
Quantum nonlocal theory of topological Fermi arc plasmons in Weyl semimetals
The surface of a Weyl semimetal (WSM) displays Fermi arcs, i.e., disjoint segments of a two-dimensional Fermi contour. We present a quantum-mechanical nonlocal theory of chiral Fermi arc plasmons in
Sound of Fermi arcs: a linearly dispersing gapless surface plasmon mode in undoped Weyl semimetals
Using Green's function of semi-infinite Weyl semimetals we find that the collective charge excitations of Fermi arcs in undoped Weyl semi-metals are linearly dispersing gapless plasmon modes. The
Excitonic collective modes in Weyl semimetals
Weyl semi-metals are three dimensional generalizations of graphene with point-like Fermi surfaces. Their linear electronic dispersion leads to a window in the particle-hole excitation spectrum which
Characterization of a Weyl semimetal using a unique feature of surface plasmon polaritons
We theoretically investigate the decay constant of surface plasmon polaritons in a Weyl semimetal and propose an experimental method for detecting Weyl semimetals. It is revealed that the surface
Acoustic plasmons in type-I Weyl semimetals
Massless chiral fermions emergent in inversion symmetry-breaking Weyl semimetals (WSMs) reside in the vicinity of multiple low symmetry nodes and thus acquire strongly anisotropic dispersion. We
Dynamical density and spin response of Fermi arcs and their consequences for Weyl semimetals
Weyl semimetals exhibit exotic Fermi-arc surface states, which strongly affect their electromagnetic properties. We derive analytical expressions for all components of the composite density-spin
Optical properties and electromagnetic modes of Weyl semimetals
We present systematic theoretical studies of both bulk and surface electromagnetic eigenmodes, or polaritons, in Weyl semimetals. We derive the tensors of bulk and surface conductivity taking into
Green's function of semi-infinite Weyl semimetals
We classify all possible boundary conditions (BCs) for a Weyl material into two classes: (i) BC that mixes the spin projection but does not change the chirality attribute, and (ii) BC that mixes the
Giant tunable nonreciprocity of light in Weyl semimetals
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 curvature, allows one
Quantum oscillations in Dirac magnetoplasmons
The plasmon frequency in standard electron gases with a parabolic single-particle dispersion is a purely classical quantity that is not sensitive to electron interactions or the equation of state. We


Surface plasmon polaritons in topological Weyl semimetals
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 induces an
Experimental discovery of Weyl semimetal TaAs
Weyl semimetals are a class of materials that can be regarded as three-dimensional analogs of graphene breaking time reversal or inversion symmetry. Electrons in a Weyl semimetal behave as Weyl
Current at a distance and resonant transparency in Weyl semimetals
Surface Fermi arcs are the most prominent manifestation of the topological nature of Weyl semimetals. In the presence of a static magnetic field oriented perpendicular to the sample surface, their

Recently synthesized three-dimensional materials with Dirac spectrum exhibit peculiar electric transport qualitatively different from its two-dimensional analog, graphene. By neglecting impurity
Plasmon mode as a detection of the chiral anomaly in Weyl semimetals
Weyl semimetals are one kind of three-dimensional gapless semimetal with nontrivial topology in the momentum space. The chiral anomaly in Weyl semimetals manifests as a charge imbalance between the
Discovery of a Weyl fermion semimetal and topological Fermi arcs
The experimental discovery of a Weyl semimetal, tantalum arsenide (TaAs), using photoemission spectroscopy, which finds that Fermi arcs terminate on the Weyl fermion nodes, consistent with their topological character.
Quantum oscillations from surface Fermi arcs in Weyl and Dirac semimetals.
It is found that the open Fermi arcs participate in unusual closed magnetic orbits by traversing the bulk of the sample to connect opposite surfaces, and result in quantum oscillations that contain observable signatures of the topological character of the bulk Weyl semimetal.
Weyl semimetal in a topological insulator multilayer.
The Weyl semimetal has a nonzero dc conductivity at zero temperature, but Drude weight vanishing as T(2), and is thus an unusual metallic phase, characterized by a finite anomalous Hall conductivity and topologically protected edge states.
Unconventional electromagnetic mode in neutral Weyl semimetals
We study light propagation in a neutral Weyl semimetal with the Fermi level lying at the Weyl nodes in the weak self-interacting regime. The nontrivial topology induces a screening effect in one of

We investigate novel phases that emerge from the interplay of electron correlations and strong spin-orbit interactions. We focus on describing the topological semimetal, a three-dimensional phase of
