Electron vortices appear in the wake of a finite length laser pulse propogating in the underdense plasma. Usually they form two chains of vortices with opposite signs of the magnetic fields locked inside an electron cavity. Using 2D PIC simulations, we discuss the effects of evolution of single and binary electron vortices. Single electron vortices, though being in a quasistationary state on electron timescales, evolve on ion timescales, leading to anisotropic multishell ion motion.
