Emergence of multiple zero modes bound to vortices in extended topological Josephson junctions
Adrian Reich, Kiryl Piasotski, Eytan Grosfeld +1
We study planar Josephson junctions formed on the surface of a three-dimensional topological insulator (Fu-Kane proposal). We examine the experimentally relevant parameter regimes…

Current Flow in Topological Insulator Josephson Junctions due to Imperfections
Kiryl Piasotski, Omri Lesser, Adrian Reich +5
Recent experiments on planar superconductor-topological insulator-superconductor (S-TI-S) junctions, e.g., in Corbino geometry, have reported low-temperature nonzero Josephson curr…

Topological Josephson vortices at finite voltage bias
Kiryl Piasotski, Adrian Reich, Alexander Shnirman
We study the effects of finite voltage bias on Caroli-de Gennes-Matricon (CdGM) states in topological Josephson junctions with a vortex lattice. The voltage drives vortices into st…
