A spatially homogeneous, time-dependent, electric field can produce charged particle pairs from the vacuum. When the electric field is constant, the mean number of pairs which are produced depends on the electric field and the coupling…
In quantum electrodynamics, Schwinger showed in 1951 that in a uniform electric field the vacuum may spontaneously produce electron-positron pairs. For this to occur, the required electric field is exceptionally large, $\sim 10^{18}$ N/C.…
