Electronic properties and topological aspects of graphene nanohelicoids
Xiaoqian Liu, Arsen Herasymchuk, Yaroslav Zhumagulov +1
We introduce graphene nanohelicoids, geometric analogues of graphene nanoribbons, in which the honeycomb lattice is embedded on a helicoidal surface. Starting from the three-dimens…

Magnetoelectric Switching of Magnetic Order in Rhombohedral Graphene
Kilian Krötzsch, 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…

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 -layer graphene due to two-valley Coulomb interactions within a low-energy framework. Anal…
