While a monolayer PtSe 2 film is a semiconductor with interesting spin structure, bulk PtSe 2
crystal has been predicted to be a topological Dirac semimetal that can host a new type of …

The electrodynamics of topological insulators (TIs) is described by modified Maxwell's
equations, which contain additional terms that couple an electric field to a magnetization and …

We propose a correspondence between the description of emergent Lorentz symmetry in
condensed-matter systems and the established general effective field theory for Lorentz …

The discovery of topological insulators, materials with bulk band gaps and protected cross-
gap surface states in compounds such as Bi2Se3, has generated much interest in identifying …

Magneto-optical studies of Weyl semimetals have been proposed as a versatile tool for
observing low-energy Weyl fermions in candidate materials including the chiral Landau …

We report on the electronic structure of the elemental topological semimetal α− Sn on InSb
(001). High-resolution angle-resolved photoemission data allow us to observe the …

It is well established that topological insulators sustain Dirac fermion surface states as a
consequence of band inversion in the bulk. These states have a helical spin polarization …

Terahertz photoconductivity in heterostructures based on n-type Hg 1− x Cd x Te epitaxial
films both in the topological phase (x< 0.16, inverted band structure, zero band gap) and the …

The electronic structure of α-Sn (001) thin films strained compressively in-plane was studied
both experimentally and theoretically. A new topological surface state (TSS) located entirely …

Due to strong spin-orbit coupling, charge carriers in three-dimensionsal quadratic-band-
touching Luttinger semimetals have nontrivial wave functions characterized by a pseudospin …
