Kitaev spin liquid in superconducting networks
Guilherme Delfino, Mehmet Dede, Dmitry Green +3
We propose a realization of the Kitaev honeycomb Hamiltonian -- an archetypal spin-liquid model -- in a superconducting metamaterial. The architecture consists of Cooper-pair boxes…
Long-range phase coherence and phase patterns in hybrid Josephson junction arrays
Xi Wang, Asbjørn C. C. Drachmann, Candice Thomas +5
The coherence of superconductivity and its suppression near a quantum phase transition is governed by the interplay between local pairing and macroscopic phase coherence. Using sca…
Automated in situ optimization and disorder mitigation in a quantum device
Jacob Benestad, Torbjørn Rasmussen, Bertram Brovang +9
We investigate automated in situ optimization of the potential landscape in a quantum point contact device, using a gate array patterned atop the constriction. Optimiz…
Phase-Biased Andreev Diffraction Grating
Magnus R. Lykkegaard, Anders Enevold Dahl, Karsten Flensberg +3
In optical diffraction, the phase difference between sources in a grating or multi-slit mask is determined by the angle to the imaging screen, yielding the familiar multi-lobed dif…
Bends In Nanotubes Allow Electric Spin Control and Coupling
K. Flensberg, C. M. Marcus
We investigate combined effects of spin-orbit coupling and magnetic field in carbon nanotubes containing one or more bends along their length. We show how bends can be used to prov…
