(Université Grenoble Alpes) Houzet, Manuel (Université Grenoble Alpes) Nazarov, Y.V. (TU Delft QN/Nazarov Group; Kavli institute of nanoscience Delft) Date 2020 Abstract We show that the annihilation dynamics of excess quasiparticles in superconductors may result in the spontaneous formation of large spin-polarized clusters. This presents a novel scenario for spontaneous spin polarization. We estimate the relevant scales for aluminum, finding the feasibility of clusters with total spin S≃10^{4}ℏ that could be spread over microns. The fluctuation dynamics of such large spins may be detected by measuring the flux noise in a loop hosting a cluster.
