摘要：

We consider-within QED(2)-the backreaction to the Schwinger pair creation in a time dependent, spatially homogeneous electric field. Our focus is the screening of the external field as a quench and the subsequent long-term evolution of the resulting electric field. Our numerical solutions of the self consistent, fully backreacted dynamical equations exhibit a self-sustaining oscillation of both the electric field and the pair number depending on the coupling strength.
