Majorana quasiparticles in condensed matter

R Aguado - La Rivista del Nuovo Cimento, 2017 - Springer
In the space of less than one decade, the search for Majorana quasiparticles in condensed
matter has become one of the hottest topics in physics. The aim of this review is to provide a …

Magnetic-field-dependent quasiparticle dynamics of nanowire single-Cooper-pair transistors

J Van Veen, A Proutski, T Karzig, DI Pikulin… - Physical Review B, 2018 - APS
Parity control of superconducting islands hosting Majorana zero modes (MZMs) is required
to operate topological qubits made from proximitized semiconductor nanowires. We test this …

Josephson effect in multiterminal topological junctions

A Zazunov, R Egger, M Alvarado, AL Yeyati - Physical Review B, 2017 - APS
We study the Josephson effect in a trijunction formed by two topological superconductor (TS)
wires and a conventional s-wave superconductor. Using a boundary Green's function …

Analytic approach to transport in superconducting junctions with arbitrary carrier density

F Setiawan, J Hofmann - Physical Review Research, 2022 - APS
Particle transport across junctions between two superconductors is commonly described
using a simplifying approximation (often called the Andreev approximation), which assumes …

Quench dynamics of the Josephson current in a topological Josephson junction

D Sun, J Liu - Physical Review B, 2018 - APS
The 4 π-periodic Josephson effect is a distinguishing feature of a topological Josephson
junction. However, stringent conditions make it hard to observe in experiments. In this work …
