parafermionic hinge states in a three-dimensional array of coupled nanowires
Sarthak Girdhar, Viktoriia Pinchenkova, Even Thingstad +1
We construct a model of a three-dimensional helical second-order topological superconductor formed by an array of weakly coupled Rashba nanowires. We identify the parameter regime…

Robust Tripartite Entanglement Generation via Correlated Noise in Spin Qubits
Sander Driessen, Ji Zou, Even Thingstad +2
We investigate the generation of genuine tripartite entanglement in a triangular spin-qubit system due to spatially correlated noise. In particular, we demonstrate how the formatio…

Cavity-enhanced superconductivity via band engineering
Valerii K. Kozin, Even Thingstad, Daniel Loss +1
We consider a two-dimensional electron gas interacting with a quantized cavity mode. We find that the coupling between the electrons and the photons in the cavity enhances the supe…
