Microwave Signatures of Topological Superconductivity in Planar Josephson Junctions

1 min read

Theory of radio-frequency SQUID and microwave-absorption observables intended to distinguish topological gap reopening from a dense background of trivial Andreev states in realistic wide planar junctions.

Key Results

  • Predicts a resonance-frequency-shift signature across the topological transition.
  • Identifies a half-slope feature in microwave absorption.
  • Explicitly treats the diagnostic ambiguity created by many trivial Andreev bound states.
