• #### The Schwinger formula revisited II (a mathematical treatment). ﻿

(2003)
Article
Open Access
In this paper we study the production of pairs in no-analytic potentials. It is a well-known fact that, when the potential is analytic the average number of produced pairs is exponentially small in ?. On the other hand, when ...
• #### The semiclassical theory of quantized fields in classical electromagnetic backgrounds ﻿

(2003)
Article
Open Access
We show the mathematical formulation of the process of pair production in electromagnetic fields for spinless particles. We compute the probability that ? pairs are created in the semiclassical approximation, and we prove ...
