Half-integer charge injection by a Josephson junction without excess noise
F. Hassler, A. Grabsch, M. J. Pacholski +4
A Josephson junction in a topological superconductor can inject a charge e/2 into a normal-metal contact, carried by chiral Majorana edge modes. Here we address the question whethe…
Localization landscape for Dirac fermions
G. Lemut, M. J. Pacholski, O. Ovdat +3
In the theory of Anderson localization, a landscape function predicts where wave functions localize in a disordered medium, without requiring the solution of an eigenvalue problem.…
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…
Time-resolved electrical detection of chiral edge vortex braiding
I. Adagideli, F. Hassler, A. Grabsch +2
A phase shift across a Josephson junction in a topological superconductor injects vortices into the chiral edge modes at opposite ends of the junction. When two vortices are f…
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…
Capacitance and charge relaxation resistance of chaotic cavities - Joint distribution of two linear statistics in the Laguerre ensemble of random matrices
Aurélien Grabsch, Christophe Texier
We consider the AC transport in a quantum RC circuit made of a coherent chaotic cavity with a top gate. Within a random matrix approach, we study the joint distribution for the mes…
