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…
Berezinskii-Kosterlitz-Thouless transitions in a topological superconductor-ferromagnet-superconductor junction
Adrian Reich, Dmitriy S. Shapiro, Alexander Shnirman
We investigate quantum phase transitions in a topological Josephson junction with an embedded ferromagnetic layer, revealing a rich landscape of critical phenomena. The low-energy…
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…
Binding zero modes with fluxons in Josephson junctions of time-reversal invariant topological superconductors
Gabriel F. RodrÃguez Ruiz, Adrian Reich, Alexander Shnirman +2
We study the joint dynamics of the phase bias and the propagating Majorana fermions of the edge modes in Josephson junctions containing 2D time-reversal invariant topological…
