Directional control of charge and valley currents in a graphene-based device
M. Berdakin, J. E. Barrios Vargas, L. E. F. Foa Torres
We propose a directional switching effect in a metallic device. To such end we exploit a graphene-based device with a three-terminal geometry in the presence of a magnetic field. W…

Topological states of non-Hermitian systems
V. M. Martinez Alvarez, J. E. Barrios Vargas, M. Berdakin +1
Recently, the search for topological states of matter has turned to non-Hermitian systems, which exhibit a rich variety of unique properties without Hermitian counterparts. Lattice…
