Vortrag von Prof. Piet Brouwer von der Freien Universität Berlin:
A one dimensional spinless p-wave superconductor may be in a
topological nontrivial state, in which it has a zero energy Majorana
bound state at each end. Although no known materials are spinless
p-wave superconductors, such a system can be realized in principle in
spin-orbit coupled nanowires with proximity-induced pairing from a
nearby s-wave superconductor. After introducing the topological phase,
I will discuss how non-idealities, such as potential disorder and
deviations from a strict one-dimensional limit, affect the topological
phase and its possible experimental signatures.
