Abstract

In this talk I will present three recent results (one published and
two in progress) about long Josephson junctions formed in heterostructures
consisting of topological insulators, superconductors and ferromagnetic
insulators (Kane-Fu proposal). First I will discuss the current-phase relation and
identify the roles played by the Andreev bound states and by the scattering states
of the continuum. Next I will describe the formation of Majorana zero modes
when an external magnetic field is applied. Finally, I will sketch some ideas about
magnetisation dynamics is such junctions.
