Spin spectroscopy of a hybrid superconducting nanowire using side-coupled quantum dots

We investigate superconducting hybrid nanowires defined by patterned gates on a two-dimensional het-erostructure of InAs and Al, with lateral quantum dots operating as single-level spectrometers along the side of the nanowire. Applying magnetic field along the wire axis spin splits dot levels, providing spin-resolved spectroscopy. We investigate spin and charge polarizations of subgap states in the nanowire and their evolution with magnetic field and gate voltage.

Automated summary

In this study, we investigate superconducting hybrid nanowires consisting of patterned gates on a two-dimensional heterostructure of InAs and Al. Lateral quantum dots are used as single-level spectrometers to analyze the subgap states and their polarizations in the nanowire. By applying a magnetic field and adjusting the gate voltage, we study the spin and charge polarizations and their changes in the nanowire.
