Time scales for charge-transfer based operations on Majorana systems
R. Seoane Souto, K. Flensberg, M. Leijnse
In this article we analyze the efficiency of operations based on transferring charge from a quantum dot (QD) to two coupled topological superconductors, which can be used for perfo…
Weak measurement protocols for Majorana bound state identification
Jan Manousakis, Carolin Wille, Alexander Altland +3
We propose a continuous weak measurement protocol testing the nonlocality of Majorana bound states through current shot noise correlations. The experimental setup contains a topolo…
Absence of supercurrent sign reversal in a topological junction with a quantum dot
J. Schulenborg, K. Flensberg
Experimental techniques to verify Majoranas are of current interest. A prominent test is the effect of Majoranas on the Josephson current between two wires linked via a normal junc…
Conductance-matrix symmetries of a three-terminal hybrid device
G. C. Ménard, G. L. R. Anselmetti, E. A. Martinez +10
We present conductance-matrix measurements of a three-terminal superconductor-semiconductor hybrid device consisting of two normal leads and one superconducting lead. Using a symme…
Nonlocal conductance spectroscopy of Andreev bound states: Symmetry relations and BCS charges
Jeroen Danon, Anna Birk Hellenes, Esben Bork Hansen +3
Two-terminal conductance spectroscopy of superconducting devices is a common tool for probing Andreev and Majorana bound states. Here, we study theoretically a three-terminal setup…
Current-induced gap opening in interacting topological insulator surfaces
Ajit C. Balram, Karsten Flensberg, Jens Paaske +1
Two-dimensional topological insulators (TIs) host gapless helical edge states that are predicted to support a quantized two-terminal conductance. Quantization is protected by time-…
