Probing the chirality of 1D Majorana edge states around a 2D nanoflake in a superconductor
Andrzej Ptok, David J. Alspaugh, Szczepan Głodzik +4
The interplay between superconductivity, magnetic field and spin-orbit coupling can lead to the realization of non--trivial topological phases. Recent experiments have found signat…

Volkov-Pankratov states in topological superconductors
David J. Alspaugh, Daniel E. Sheehy, Mark O. Goerbig +1
We study the in-gap states that appear at the boundaries of both 1D and 2D topological superconductors. While the massless Majorana quasiparticles are guaranteed to arise by the bu…

Proximity-Induced Superconductivity at Non-Helical Topological Insulator Interfaces
David J. Alspaugh, Mahmoud M. Asmar, Daniel E. Sheehy +1
We study how non-helical spin textures at the boundary between a topological insulator (TI) and a superconductor (SC) affect the proximity-induced superconductivity of the TI inter…
