Transport in magnetic-topological-insulator nanoribbons containing multiple superconductor-proximitized sectors
Javier Osca, Sungguen Ryu, Rosa López +1
Transport in devices with multiple proximitized sectors depends heavily on the complex phases of the pairing gaps of those sectors. We investigate magnetic topological insulator na…
Electrostatic gating and the interference of chiral Majoranas in thin slabs of magnetic topological insulators
Javier Osca, Llorenç Serra
We study the interference of chiral Majoranas in a magnetic topological insulator thin slab having a grounded section proximity coupled to a superconductor and another section unde…
Characterizing and Mitigating Timing Noise-Induced Decoherence in Single Electron Sources
Sungguen Ryu, Rosa López, Llorenç Serra +2
Identifying and controlling decoherence in single electron sources (SES) is important for their applications in quantum information processing. The recent experiments with ultrasho…
Conductance oscillations and speed of chiral Majorana mode in a quantum-anomalous-Hall 2d strip
Javier Osca, Llorenç Serra
We predict conductance oscillations in a quantum-anomalous Hall 2d strip having a superconducting region of length with a chiral Majorana mode. These oscillations require a f…
Quasi-particle current in planar Majorana nanowires
Javier Osca, Llorenç Serra
We calculate the local quasi-particle current of a Majorana state in a planar hybrid (superconductor-semiconductor) nanowire. In absence of perpendicular components of the magnetic…
Majorana states and magnetic orbital motion in planar hybrid nanowires
Javier Osca, Llorenç Serra
The Majorana phase boundaries in planar 2D hybrid (semiconductor-superconductor) nanowires are modified by orbital effects due to off plane magnetic components. We show that Majora…
Majorana modes in smooth normal-superconductor nanowire junctions
Javier Osca, Llorens Serra
A numerical method to obtain the spectrum of smooth normal-superconductor junctions in nanowires, able to host Majorana zero modes, is presented. Softness in the potential and supe…
