Voltage staircase in a current-biased quantum-dot Josephson junction
D. O. Oriekhov, Y. Cheipesh, C. W. J. Beenakker
We calculate the current-voltage (I-V) characteristic of a Josephson junction containing a resonant level in the weakly coupled regime (resonance width small compared to the superc…
Dynamical signatures of ground-state degeneracy to discriminate against Andreev levels in a Majorana fusion experiment
A. Grabsch, Y. Cheipesh, C. W. J. Beenakker
Detection of the fusion rule of Majorana zero-modes is a near-term milestone on the road to topological quantum computation. An obstacle is that the non-deterministic fusion outcom…
Pfaffian formula for fermion parity fluctuations in a superconductor and application to Majorana fusion detection
A. Grabsch, Y. Cheipesh, C. W. J. Beenakker
Kitaev's Pfaffian formula equates the ground-state fermion parity of a closed system to the sign of the Pfaffian of the Hamiltonian in the Majorana basis. Using Klich's theory of f…
