Flat bands and gaps in twisted double bilayer graphene
F. J. Culchac, Rodrigo B. Capaz, Leonor Chico +1
We present electronic structure calculations of twisted double bilayer graphene (TDBG): A tetralayer graphene structure composed of two AB-stacked graphene bilayers with a relative…
Photonic spin Hall effect in bilayer graphene Moiré superlattices
W. J. M. Kort-Kamp, F. J. Culchac, Rodrigo B. Capaz +1
The formation of a superstructure - with a related Moiré pattern - plays a crucial role in the extraordinary optical and electronic properties of twisted bilayer graphene, includin…
Spin waves in zigzag graphene nanoribbons and the stability of edge ferromagnetism
F. Culchac, A. Latge, A. T. Costa
We study the low energy spin excitations of zigzag graphene nanoribbons of varying width. We find their energy dispersion at small wave vector to be dominated by antiferromagnetic…
