Proposal for the detection and braiding of Majorana fermions in a quantum spin Hall insulator
Shuo Mi, D. I. Pikulin, M. Wimmer +1
We show how a quantum dot with a ballistic single-channel point contact to a superconductor can be created by means of a gate electrode at the edge of a quantum spin Hall insulator…
Zero-voltage conductance peak from weak antilocalization in a Majorana nanowire
D. I. Pikulin, J. P. Dahlhaus, M. Wimmer +2
We show that weak antilocalization by disorder competes with resonant Andreev reflection from a Majorana zero-mode to produce a zero-voltage conductance peak of order e^2/h in a su…
Andreev reflection from a topological superconductor with chiral symmetry
M. Diez, J. P. Dahlhaus, M. Wimmer +1
It was pointed out by Tewari and Sau that chiral symmetry (H -> -H if e <-> h) of the Hamiltonian of electron-hole (e-h) excitations in an N-mode superconducting wire is associated…
Barrier transmission of Dirac-like pseudospin-one particles
D. F. Urban, D. Bercioux, M. Wimmer +1
We address the problem of barrier tunneling in the two-dimensional T_3 lattice (dice lattice). In particular we focus on the low-energy, long-wavelength approximation for the Hamil…
Weak localization in mesoscopic hole transport: Berry phases and classical correlations
Viktor Krueckl, Michael Wimmer, Inanc Adagideli +2
We consider phase-coherent transport through ballistic and diffusive two-dimensional hole systems based on the Kohn-Luttinger Hamiltonian. We show that intrinsic heavy-hole light-h…
