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…

Wigner-Smith matrix, exponential functional of the matrix Brownian motion and matrix Dufresne identity
Aurélien Grabsch, Christophe Texier
We consider a multichannel wire with a disordered region of length and a reflecting boundary. The reflection of a wave of frequency is described by the scattering matrix $\…
