Evidence of 3D Dirac conical bands in TlBiSSe by optical and magneto-optical spectroscopy

F. Le Mardelé, J. Wyzula, I. Mohelsky +15

TlBiSSe is a rare realization of a 3D semimetal with a conically dispersing band that has an optical response which is well isolated from other contributions in a broad range of ph…

Prediction and observation of the first antiferromagnetic topological insulator

Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41

Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
