Controlling non-Abelian statistics of Majorana fermions in semiconductor nanowires
Under appropriate external conditions a semiconductor nanowire in proximity to an s-wave superconductor can be in a topological superconducting (TS) phase. This phase supports localized zero-energy… Expand

Motivated by an important recent experiment [Deng , Science 354, 1557 (2016)SCIEAS0036-807510.1126/science.aaf3961], we theoretically consider the interplay between Andreev and Majorana bound states… Expand

We show that an ordinary semiconducting thin film with spin-orbit coupling can, under ap- propriate circumstances, be in a quantum topologically ordered state supporting exotic Majorana excitations… Expand
Topological invariants for spin-orbit coupled superconductor nanowires.
We show that the Hamiltonian of a multiband spin-orbit coupled semiconductor nanowire with Zeeman splitting and s-wave superconductivity is approximately chiral symmetric. The chiral symmetry becomes… Expand
