Electronic properties and topological aspects of graphene nanohelicoids

Xiaoqian Liu, Arsen Herasymchuk, Yaroslav Zhumagulov +1

The paper introduces graphene nanohelicoids—helically wrapped graphene nanoribbons—and uses tight‑binding calculations to show that their electronic band structures exhibit width‑d…

Correlated phases in rhombohedral multilayer graphene

Arsen Herasymchuk, Sergei G. Sharapov, Oleg V. Yazyev +1

We investigate the emergence of correlated electron phases in rhombohedral $N$ -layer graphene due to two-valley Coulomb interactions within a low-energy $k \cdot p$ framework. Anal…

Magnetoelectric Switching of Magnetic Order in Rhombohedral Graphene

Kilian KrÃ¶tzsch, Arsen Herasymchuk, Yaroslav Zhumagulov +6

A finite Hall conductance under zero magnetic field implies time reversal symmetry (TRS) breaking due to magnetic order. In rhombohedral stacked multilayer graphene, the angular mo…
