Long-lived circulating currents in strongly correlated nanorings
B. M. Schoenauer, N. M. Gergs, P. Schmitteckert +2
We study the time evolving currents flowing in an interacting, ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expecte…
Non-Topological Majorana Zero Modes in Inhomogeneous Spin Ladders
Neil J. Robinson, Alexander Altland, Reinhold Egger +6
We show that the coupling of homogeneous Heisenberg spin-1/2 ladders in different phases leads to the formation of interfacial zero energy Majorana bound states. Unlike Majorana bo…
Spin switching via quantum dot spin valves
N. M. Gergs, S. A. Bender, R. A. Duine +1
We develop a theory for spin transport and magnetization dynamics in a quantum-dot spin valve, i.e., two magnetic reservoirs coupled to a quantum dot. Our theory is able to take in…
Topological order in the Kitaev/Majorana chain in the presence of disorder and interactions
Niklas M. Gergs, Lars Fritz, Dirk Schuricht
We study the combined effect of interactions and disorder on topological order in one dimension. To this end we consider a generalized Kitaev chain including fermion-fermion intera…
Charge fluctuations in nonlinear heat transport
Niklas M. Gergs, Christoph B. M. Hörig, Maarten R. Wegewijs +1
We show that charge fluctuation processes are crucial for the nonlinear heat conductance through an interacting nanostructure, even far from a resonance. We illustrate this for an…
