Dynamical Schwinger process in a bifrequent electric field of finite duration: survey on amplification
The electron-positron pair production due to the dynamical Schwinger process
in a slowly oscillating strong electric field is enhanced by the superposition
of a rapidly oscillating weaker electric field. A systematic account of the
enhancement by the resulting bifrequent field is provided for the residual
phase space distribution. The enhancement is explained by a severe reduction of
the suppression in both the tunneling and multiphoton regimes
