Shot noise, originating from the discrete nature of electric charge, is generated by scattering
processes. Shot-noise measurements have revealed microscopic charge dynamics in …

Majorana fermions are the only fermionic particles that are expected to be their own
antiparticles. Although elementary particles of the Majorana type have not been identified …

We report on transport measurements of an InAs nanowire coupled to niobium nitride leads
at high magnetic fields. We observe a zero-bias anomaly (ZBA) in the differential …

Spectroscopic measurements with low-temperature scanning tunneling microscopes have
been used very successfully for studying not only individual atomic or molecular spins on …

The spectrum of a segment of InAs nanowire, confined between two superconducting leads,
was measured as function of gate voltage and superconducting phase difference using a …

We present a solver for correlated impurity problems out of equilibrium based on a
combination of the so-called auxiliary master equation approach (AMEA) and the …

Quantum impurity models, which describe how a local degree of freedom interacts with a
continuum, are central to condensed-matter physics. Such models may be naturally …

The numerical renormalization group (NRG) is tailored to describe interacting impurity
models in equilibrium, but it faces limitations for steady-state nonequilibrium, arising, eg, due …

Subgap states in semiconducting-superconducting nanowire hybrid devices are
controversially discussed as potential topologically nontrivial quantum states. One source of …

We study the properties of a quantum dot coupled to a topological superconductor and a
normal lead and discuss the interplay between Kondo-and Majorana-induced couplings in …
