Topological nodal semimetals
A. A. Burkov, M. D. Hook, Leon Balents
We present a study of "nodal semimetal" phases, in which non-degenerate conduction and valence bands touch at points (the "Weyl semimetal") or lines (the "line node semimetal") in…
Weyl Semimetal in a Topological Insulator Multilayer
A. A. Burkov, Leon Balents
We propose a simple realization of the three-dimensional (3D) Weyl semimetal phase, utilizing a multilayer structure, composed of identical thin films of a magnetically-doped 3D to…
Thin topological insulator film in a perpendicular magnetic field
A. A. Zyuzin, A. A. Burkov
We report on a study of an ultrathin topological insulator film with hybridization between the top and bottom surfaces, placed in a quantizing perpendicular magnetic field. We calc…
Parallel magnetic field driven quantum phase transition in a thin topological insulator film
A. A. Zyuzin, M. D. Hook, A. A. Burkov
It is well-known that helical surface states of a three-dimensional topological insulator (TI) do not respond to a static in-plane magnetic field. Formally this occurs because the…
