Multi-Quanta Abrikosov Vortices as the Micro Spin Batteries

The aim of our paper is to study the multi-quanta Abrikosov vortices injected into a superconductor layer by twisted light impulses. We predict that the condensate circulating around the core of a multi-quanta vortex may differ in nature from that of the bulk superconductor. Special attention is paid to the possibility of the appearance of quasi-angular momentum of Cooper pairs and its compensation via their recombination to fermion quartets. We show potential applications of multi-quanta vortices as massive memories, as well as spin, angular momentum, and energy batteries. Finally, we predict the emergence of half-quantum multi-quanta Josephson vortices under certain conditions.
