Physical phenomena in strong background fields differ from those in weak ones. The production of charged particle pairs in a strong electric field, known as the Schwinger effect, is one of the most prominent aspects of nonperturbative quantum electrodynamics (QED), and Hawking radiation from black holes is another phenomenon; both of which cannot be found by the weak field method.
Heisenberg-Euler and Schwinger [1] found the one-loop effective action in a strong constant electromagnetic field by computing the interactions of the negative-energy electrons in the Dirac sea with all even numbers of photons from the background electromagnetic field (see Fig.~\ref{fig:field_conf}), and showed that the Dirac vacuum under such a field becomes a polarized medium [2].
When the electric field is comparable to the critical field $E_{c} = m^2c^3/e\hbar = 1.3 \times 10^{16}\, {\rm V/cm}$, electron-positron pairs are significantly produced to have the mean number of pairs as
\begin{equation*}
{\cal N} (E) = e^{-\frac{\pi m^2}{eE}},
\end{equation*}
where we use the cgs Gaussian units with $c=\hbar =1$.
