Disorder-induced topological transitions in multichannel Majorana wires
B. Pekerten, A. Teker, O. Bozat +2
In this work, we investigate the effect of disorder on the topological properties of multichannel superconductor nanowires. While the standard expectation is that the spectral gap…
Effects of electron scattering on the topological properties of nanowires: Majorana fermions from disorder and superlattices
I. Adagideli, M. Wimmer, A. Teker
We focus on inducing topological state from regular, or irregular scattering in (i) p-wave superconducting wires and (ii) Rashba wires proximity coupled to an s-wave superconductor…
Symmetries and the conductance of graphene nanoribbons with long-range disorder
J. Wurm, M. Wimmer, K. Richter
We study the conductance of graphene nanoribbons with long-range disorder. Due to the absence of intervalley scattering from the disorder potential, time-reversal symmetry (TRS) ca…
Interfaces Within Graphene Nanoribbons
J. Wurm, M. Wimmer, I. Adagideli +2
We study the conductance through two types of graphene nanostructures: nanoribbon junctions in which the width changes from wide to narrow, and curved nanoribbons. In the wide-narr…
Graphene Rings in Magnetic Fields: Aharonov-Bohm Effect and Valley Splitting
J. Wurm, M. Wimmer, H. U. Baranger +1
We study the conductance of mesoscopic graphene rings in the presence of a perpendicular magnetic field by means of numerical calculations based on a tight-binding model. First, we…
Extracting current-induced spins: spin boundary conditions at narrow Hall contacts
I. Adagideli, M. Scheid, M. Wimmer +2
We consider the possibility to extract spins that are generated by an electric current in a two-dimensional electron gas with Rashba-Dresselhaus spin-orbit interaction (R2DEG) in t…
