Pair Creation in Electric Fields, Anomalies, Renormalization, and Backreaction |
|
Abstract |
We consider pair production phenomena in spatially homogeneous strong electric fields. We first study scalar QED in four-dimensions and discuss the potential ambiguity in the adiabatic order assignment for the electromagnetic potential required to fix the renormalization subtractions. This ambiguity can be fixed by invoking the conformal anomaly when both electric and gravitational backgrounds are present. We also extend the adiabatic regularization method for spinor QED in two-dimensions and find consistency with the chiral anomaly. We have studied numerically the semiclassical Maxwell equations with the adiabatic subtraction terms of the proper adiabatic order. |
