One of the most important technological inventions during the last century was the transistor, which has enabled the subsequent computational revolution. For future progress in this field two main… Expand
Topological order in the Kitaev/Majorana chain in the presence of disorder and interactions
We study the combined effect of interactions and disorder on topological order in one dimension. Toward that end, we consider a generalized Kitaev chain including fermion-fermion interactions and… Expand
Charge fluctuations in nonlinear heat transport
We show that charge fluctuation processes are crucial for the nonlinear heat conductance through an interacting nanostructure, even far from a resonance. The often made assumption that off-resonant… Expand
Spin Switching via Quantum Dot Spin Valves.
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 into account effects… Expand
Long-lived circulating currents in strongly correlated nanorings
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 expected relaxation… Expand
Nontopological Majorana Zero Modes in Inhomogeneous Spin Ladders.
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 bound states at the… Expand
