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…
