A kutatási téma leírása:
Magnetic ordering and superconductivity have been traditionally considered to exclude each other, since a strong magnetic field breaks conventional superconducting order. It was recently discovered that at the interface between magnets and superconductors p-wave pairing emerges, giving rise to intriguing phenomena. The magnetic atoms create Yu-Shiba-Rusinov bound states in the superconductor, which combined with the p-wave pairing may lead to the formation of Majorana bound states, a promising basic element of topological quantum computers. The p-wave pairing also causes spin-polarized supercurrents to flow through the interface, which can be used to manipulate the magnetic order. In the proposed doctoral project, numerical simulations and analytical models will be applied to describe the interplay between the torques exerted by spin-polarized supercurrents on the magnetic configurations and the dynamics of Yu-Shiba-Rusinov states. The research is to be carried out using a computer simulation code developed at the institute based on Green's function and spin dynamics methods. It is planned to be explored how the spin-polarized supercurrents may be applied to influence and detect the magnetic configurations and the topology of the Yu-Shiba-Rusinov band structure in nanoscale magnetic systems on the surface of elemental superconductors. The project will provide the opportunity for collaboration with other experimental and theoretical groups within an international network.
