- Abstract: Effect of spatially oscillating fields on the electron-positron pair
production is studied numerically and analytically when the work done by the
electric field over its spatial extent is smaller than twice the electron mass.
Under large spatial scale, we further explain the characteristics of the
position and momentum distribution via tunneling time, tunneling distance and
energy gap between the positive and negative energy bands in the Dirac vacuum.
Our results show that the maximum reduced particle number is about five times
by comparing to maximum number for non-oscillating field. Moreover, the pair
production results via Dirac-Heisenberg-Wigner formalism can be also calculated
by using local density approximation and analytical approximation method when
spatial oscillating cycle number is large. Moreover, in case of large spatial
scale field, the position distribution of created particles could be
interpreted by the tunneling time.
