Fractional Josephson Vortices and Braiding of Majorana Zero Modes in Planar Superconductor-Semiconductor Heterostructures
Ady Stern, Erez Berg
We consider the one-dimensional (1D) topological superconductor that may form in a planar superconductor-metal-superconductor Josephson junction in which the metal is is subjected…
Gapless Topological Superconductors - Model Hamiltonian and Realization
Yuval Baum, Thore Posske, Ion Cosma Fulga +2
The existence of an excitation gap in the bulk spectrum is one of the most prominent fingerprints of topological phases of matter. In this paper, we propose a family of two dimensi…
Adiabatic manipulations of Majorana fermions in a three-dimensional network of quantum wires
Bertrand I. Halperin, Yuval Oreg, Ady Stern +3
It has been proposed that localized zero-energy Majorana states can be realized in a two-dimensional network of quasi-one-dimensional semiconductor wires that are proximity-coupled…
Observing Majorana bound states of Josephson vortices in topological superconductors
Eytan Grosfeld, Ady Stern
In recent years there has been an intensive search for Majorana fermion states in condensed matter systems. Predicted to be localized on cores of vortices in certain non-convention…
