Missing Shapiro steps in topologically trivial Josephson junction on InAs quantum well

Recent observations of missing odd Shapiro steps have been interpreted in the context of topological superconductivity. Here, the authors observe missing odd Shapiro steps in topologically trivial Josephson junctions due to high transparency of the junctions, calling for caution in relationship to t...

Sumario:Recent observations of missing odd Shapiro steps have been interpreted in the context of topological superconductivity. Here, the authors observe missing odd Shapiro steps in topologically trivial Josephson junctions due to high transparency of the junctions, calling for caution in relationship to topological superconductivity.
