Superconductivity 2015-02-19 v2

Abstract

We study the topologically protected Majorana zero modes induced by lattice dislocations in chiral topological superconductors. Dislocations provide a new way to realize Majorana zero modes at zero magnetic field. In particular, we study several different types of dislocations in the candidate material Sr2RuO4.{\rm Sr_2RuO_4}. We also discuss the properties of linked dislocation lines and linked dislocation and flux lines. Various experimental consequences are predicted which provide a new approach to determine whether nature of the superconducting phase of Sr2RuO4.{\rm Sr_2RuO_4}.
