Detection of second-order topological superconductors by Josephson junctions
Song-Bo Zhang, Björn Trauzettel
Abstract
This work uncovers the role of chemical potential in a second order topological superconductor. It results in a zero-$\ensuremath{\pi}$ transition in a Josephson junction as a function of the chemical potential. Additionally, the authors propose a novel platform for creating and manipulating Majorana bound states in a fully electric way.
