A topological superconductor is characterized by having a pairing gap in the bulk and
gapless self-hermitian Majorana modes at its boundary. In one dimension, these are zero …

We propose a setup that integrates a quantum point contact (QPC) and a Josephson
junction on a quantum spin Hall sample, experimentally realizable in InAs/GaSb quantum …

A hard proximity-induced superconducting gap has recently been observed in
semiconductor nanowire systems at low magnetic fields. However, in the topological regime …

We study a topological superconductor island with spatially separated Majorana modes
coupled to multiple normal-metal leads by single-electron tunneling in the Coulomb …

We propose a new platform to detect signatures of the presence of Majorana bound states
(MBSs) in the Fraunhofer pattern of Josephson junctions featuring quantum spin Hall edge …

We propose a novel realization for a topologically superconducting phase hosting Majorana
zero modes on the basis of quantum spin Hall systems. Remarkably, our proposal is …

We propose a universal gate set acting on a qubit formed by the degenerate ground states
of a Coulomb-blockaded time-reversal invariant topological superconductor island with …

Using the properties of the transfer matrix of one-dimensional quantum mechanical systems,
we derive an exact formula for the persistent current across a quantum mechanical ring …

For Josephson junctions based on s-wave superconductors, time-reversal symmetry is
known to allow for powerful relations between the normal-state junction properties, the …

We study multiterminal Majorana and conventional superconducting islands in the vicinity of
the charge degeneracy point using bosonization and the numerical renormalization group …
