Robust gap closing and reopening in topological-insulator Josephson junctions
Jakob Schluck, Ella Nikodem, Anton Montag +4
In the seminal proposal by Fu and Kane, the superconducting proximity effect is used to realize topological superconductivity in the topological surface state (TSS) of a 3D topolog…
Geometry-independent tight-binding method for massless Dirac fermions in two dimensions
Alexander Ziesen, Ion Cosma Fulga, Fabian Hassler
The Nielsen-Ninomiya theorem, dubbed `fermion-doubling', poses a problem for the naive discretization of a single (massless) Dirac cone on a two-dimensional surface. The inevitable…
Statistical Majorana Bound State Spectroscopy
Alexander Ziesen, Alexander Altland, Reinhold Egger +1
Tunnel spectroscopy data for the detection of Majorana bound states (MBS) is often criticized for its proneness to misinterpretation of genuine MBS with low-lying Andreev bound sta…
Low-energy in-gap states of vortices in superconductor-semiconductor heterostructures
Alexander Ziesen, Fabian Hassler
The recent interest in the low-energy states in vortices of semiconductor-superconductor heterostructures are mainly fueled by the prospects of using Majorana zero modes for quantu…
Topological ordering in the Majorana Toric Code
Alexander Ziesen, Fabian Hassler, Ananda Roy
At zero temperature, a two-dimensional lattice of Majorana zero modes on mesoscopic superconducting islands exhibits a topologically-ordered toric code phase. Recently, a Landau fi…
