Charge profile in vortices

Abstract

The electric charge density in the vortex lattice of superconductors is studied within the Ginzburg-Landau theory. We show that the electrostatic potential $\varphi$ is proportional to the GL function, $\varphi \propto |\psi {|}^2-|{\psi }_{\infty }{|}^2$. Numerical results for the triangular vortex lattice are presented.
