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…
