End states and subgap structure in proximity-coupled chains of magnetic adatoms
Michael Ruby, Falko Pientka, Yang Peng +3
A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] provides evidence for Majorana zero modes in iron (Fe) chains on the superconducting Pb(110) surface. Here, we stud…
Robust Majorana conductance peaks for a superconducting lead
Yang Peng, Falko Pientka, Yuval Vinkler-Aviv +2
Experimental evidence for Majorana bound states largely relies on measurements of the tunneling conductance. While the conductance into a Majorana state is in principle quantized t…
Tunneling processes into localized subgap states in superconductors
Michael Ruby, Falko Pientka, Yang Peng +3
We combine scanning-tunneling-spectroscopy experiments probing magnetic impurities on a superconducting surface with a theoretical analysis of the tunneling processes between (supe…
Shortcuts to nonabelian braiding
Torsten Karzig, Falko Pientka, Gil Refael +1
Topological quantum information processing relies on adiabatic braiding of nonabelian quasiparticles. Performing the braiding operations in finite time introduces transitions out o…
