EPJB Colloquium - Complex band-structure analysis and topological physics of Majorana nanowires

In this new Colloquium article published in EPJ B, Javier Osca (IMEC and KU Leuven, Belgium) and Llorenç Serra (IFISC and Departament de Física, Universitat de les Illes Balears, Palma, Spain) review applications of complex band structure theory to describe Majorana states in nanowires and nanowire junctions. The dimensionality of the considered wires is gradually increased, from strictly 1D to quasi-1D with one and two transverse dimensions.

Complex wave number analysis is applied to two main types of Majorana modes: end states in hybrid semiconductor wires and chiral edge states in hybrid wires of quantum-anomalous Hall insulators. In topological NS and NSN junctions with Majorana modes conductance oscillations and spatial distributions of density and current are described. Finally, the optical absorption in finite systems with both types of Majorana modes is considered.

This is the third time for 6 years that we have been publishing the Proceedings of the Int. Conf. NSRT in the EPJ Web of Conf, so one may say we are old friends with this wonderful publishing team. Our experience of working together with this highly professional staff has been and remains to be very positive. This time the publication procedure was especially fast. We always recommend the EPJ Web of Conf to our colleagues.
