Little–Parks oscillations of a hollow superconducting cylinder are of interest for flux-driven topological superconductivity in single Rashba nanowires. The oscillations are typically symmetric in the orientation of the applied magnetic flux. Using double InAs nanowires coated by an epitaxial superconducting Al shell which, despite the non-centro-symmetric geometry, behaves effectively as one hollow cylinder, we demonstrate that a small misalignment of the applied parallel field with respect to…

Magnetoresistance oscillations of superconducting Al-film cylinders covering InAs nanowires below the quantum critical point.
TLDR
It is shown that as d is reduced in comparison to ξ(0) the resistance attains the normal state value, which seems to be temperature independent in the vicinity of half flux quanta.
Destruction of the Global Phase Coherence in Ultrathin, Doubly Connected Superconducting Cylinders
TLDR
Transport measurements in ultrathin Al and Au0.7In0.3 cylinders verify the presence of this destructive regime characterized by the loss of the global phase coherence and reveal a phase diagram featuring disconnected phase coherent regions, as opposed to the single region seen in larger superconducting cylinders studied previously.

Andreev Interference in the Surface Accumulation Layer of Half‐Shell InAsSb/Al Hybrid Nanowires
TLDR
The gate-dependent surface accumulation layer of half-shell InAsSb/Al nanowires was studied by means of Andreev interference in a parallel magnetic field and the spatial distribution was tunable by a gate potential as expected from electrostatic models.

TLDR
