Particle-hole symmetry broken solutions in graphene nanoribbons: a multi-orbital, mean-field perspective
T. Schmirander, D. Pfannkuche, M. Prada
Mean-field theories have since long predicted edge magnetism in graphene nanoribbons, where the order parameter is given by the local magnetization. However, signatures of edge mag…
Sublattice symmetry breaking and ultra low energy excitations in Graphene-on-hBN Heterostructures
U. R. Singh, M. Prada, V. Strenzke +4
The low-lying states of graphene contain exciting topological properties that depend on the interplay of different symmetry breaking terms. The corresponding energy gaps remained u…
Nanofriction and motion of topological defects in self-organized ion Coulomb crystals
Jan Kiethe, Ramil Nigmatullin, Thorben Schmirander +2
We study nanofriction in an ion Coulomb crystal under the presence of topological defects. We observe signatures of the pinning to sliding transition, namely the transverse vibrati…
Probing Nanofriction and Aubry-type signatures in a finite self-organized system
Jan Kiethe, Ramil Nigmatullin, Dimitri Kalincev +2
Friction in ordered atomistic layers plays a central role in various nanoscale systems ranging from nanomachines to biological systems. It governs transport properties, wear and di…
