Spin-pumping and inelastic electron tunneling spectroscopy in topological insulators
Aaron Hurley, Awadhesh Narayan, Stefano Sanvito
We demonstrate that a quantum spin Hall current, spontaneously generated at the edge of a two-dimensional topological insulator, acts as a source of spin-pumping for a magnetic imp…
Topological surface states scattering in Antimony
Awadhesh Narayan, Ivan Rungger, Stefano Sanvito
In this work we study the topologically protected states of the Sb(111) surface by using ab-initio transport theory. In the presence of a strong surface perturbation we obtain stan…
Andreev reflection in two-dimensional topological insulators with either conserved or broken time-reversal symmetry
Awadhesh Narayan, Stefano Sanvito
We investigate Andreev reflection in two-dimensional heterojunctions formed by a superconductor in contact with a topological insulator ribbon either possessing or breaking time-re…
