Electrostatic effects and topological superconductivity in semiconductor-superconductor-magnetic insulator hybrid wires
Benjamin D. Woods, Tudor D. Stanescu
We investigate the impact of electrostatics on the proximity effect between a magnetic insulator and a semiconductor wire in semiconductor-superconductor-magnetic insulator hybrid…
Feasibility of measurement-based braiding in the quasi-Majorana regime of semiconductor-superconductor heterostructures
Chuanchang Zeng, Gargee Sharma, Tudor D. Stanescu +1
We discuss the feasibility of measurement-based braiding in semiconductor-superconductor (SM-SC) heterostructures in the so-called quasi-Majorana regime the topologically-trivi…
Enhanced topological protection in planar quasi-one-dimensional channels with periodically-modulated width
Benjamin D. Woods, Tudor D. Stanescu
We study one dimensional (1D) and quasi-1D periodic structures as possible platforms for the emergence of Majorana bound states with enhanced robustness against disorder and system…
Majorana versus Andreev bound state energy oscillations in a 1D semiconductor-superconductor heterostructure
Gargee Sharma, Chuanchang Zeng, Tudor D. Stanescu +1
The recent experimental observations of decaying energy oscillations in semiconductor-superconductor Majorana nanowires is in contrast with the typical expectations based on the pr…
