Electron scattering by magnetic impurity in Weyl semimetals

A. Díaz-Fernández, F. Domínguez-Adame, O. de Abril

Weyl semimetals are prominent examples of topologically protected quantum matter. These materials are the three-dimensional counterparts of graphene and great efforts are being dev…

Inducing anisotropies in Dirac fermions by periodic driving

A. Diaz-Fernandez

We consider the three-dimensional Hamiltonian for BiSe, a second-generation topological insulator, under the effect of a periodic drive for both in-plane and out-of-plane f…

Electric field manipulation of surface states in topological semimetals

Yuriko Baba, Álvaro Díaz-Fernández, Elena Díaz +2

We investigate the consequences of applying electric fields perpendicularly to thin films of topological semimetals. In particular, we consider Weyl and Dirac semimetals in a confi…

Floquet engineering of Dirac cones on the surface of a topological insulator

A. Diaz-Fernandez, E. Diaz, Álvaro Gómez-León +2

We propose to Floquet-engineer Dirac cones at the surface of a three-dimensional topological insulator. We show that a large tunability of the Fermi velocity can be achieved as a f…

Topologically protected states in -doped junctions with band inversion

A. Diaz-Fernandez, N. del Valle, E. Diaz +1

A topological boundary can be formed at the interface between a trivial and a topological insulator. The difference in the topological index across the junction leads to robust gap…

Robust midgap states in band-inverted junctions under electric and magnetic fields

A. Diaz-Fernandez, N. del Valle, F. Dominguez-Adame

Several IV-VI semiconductor compounds made of heavy atoms, such as PbSnTe, may undergo band-inversion at the point of the Brillouin zone upon variation of their c…
