New discovery

Prof. Benseman has published an article in Nature Scientific Reports demonstrating the manipulation of individual vortices in a superconducting film enabling novel high-speed low-power superconducting electronics.

This paper demonstrated a triode for single quantum magnetic field carriers, where the flow of individual magnetic vortices in a superconducting film is regulated by the magnetic potential of striae of soft magnetic strips deposited on the film surface. By rotating an applied in-plane field, the magnetic strip potential can be controlled by changes in the magnetic charges at the strip edges which accelerate or retard the motion of magnetic vortices inside the superconductor. Scaling down this design our design and reducing the gap width between the magnetic stripes will enable the manipulation of individual vortices and the creation of single flux quantum circuitry for novel high-speed low-power superconducting electronics.
