Topological insulators (TIs) hold great promise for topological quantum computation in solid-state systems. Recently, several groups reported experimental data suggesting that signatures of Majorana modes have been observed in topological insulator Josephson junctions (TIJJs). A prerequisite for the exploration of Majorana physics is to obtain a good understanding of the properties of low-energy Andreev bound states (ABSs) in a material with a topologically nontrivial band structure. Here, we…

Effect of Impurities on the Josephson Current through Helical Metals: Exploiting a Neutrino Paradigm.
The results, which are a condensed matter realization of a part of the Mikheyev-Smirnov-Wolfenstein effect for neutrinos, show that the relationship between normal state conductance and the critical current of Josephson junctions is significantly modified for Josephsonjunctions on the surface of topological insulators.
Hybrid Symmetry Epitaxy of the Superconducting Fe(Te,Se) Film on a Topological Insulator.
It is demonstrated that Fe(Te,Se) can grow epitaxially on a TI (Bi2Te3) layer due to accidental, uniaxial lattice match, which is dubbed as "hybrid symmetry epitaxy", critical to stabilizing robust superconductivity with TC as high as 13 K.

Josephson supercurrent through a topological insulator surface state.
Direct evidence for Josephson supercurrents in superconductor (Nb)-topological insulator (Bi(2)Te(3))-superconductor electron-beam fabricated junctions is provided by the observation of clear Shapiro steps under microwave irradiation, and a Fraunhofer-type dependence of the critical current on magnetic field.
Symmetry protected Josephson supercurrents in three-dimensional topological insulators.
It is shown that the supercurrent is largely carried by surface states, due to the inherent topology of the bands, and that it is robust against disorder, which clarifies key open issues regarding the nature of supercurrents in topological insulators.
Stabilization of Majorana modes in magnetic vortices in the superconducting phase of topological insulators using topologically trivial bands.
It is shown that, due to the hybridization with the trivial band, Majorana modes are preserved over a large, extended doping range for p doping, and opens a route to study other topological features of doped compounds that cannot be modeled using the simple Bi(2)Se(3) Dirac model.
