The existence of topological superconductors preserving time-reversal symmetry was recently predicted, and they are expected to provide a solid-state realization of itinerant massless Majorana fermions and a route to topological quantum computation. Their first likely example, Cu(x)Bi(2)Se(3), was discovered last year, but the search for new materials has so far been hindered by the lack of a guiding principle. Here, we report point-contact spectroscopy experiments suggesting that the low…

A comparison of the electronic states with a band-noninverted superconductor possessing a similar Fermi surface structure suggests that the anomalous behavior in the superconducting state of Sn(1-x)In(x)Te is related to the peculiar orbital characteristics of the bulk valence band and/or the presence of a topological surface state.

A simple and intuitive method of constructing the low-energy effective models for superconducting topological insulators like CuxBi2Se3 and depending on the value of the chemical potential and for experimentally relevant model parameters, theLow-energy properties of these superconductors are shown to be determined by one copy or two copies of single-orbital effective models.
