The persistent current generation in the cuprate is theoretically investigated based on the spin-vortex superconductivity theory. We present a way to impose the single-valued condition on wave functions and clarify the appearance of a vector potential and the persistent current generation by it when the spin-vortices are created by the conduction electrons. We attribute the reason for the very high superconducting transition temperature in the cuprate to the enhanced stability of the spin-vortices by the strong hole–lattice interaction.
