Pair production by and electric field in (1+1)-dimensional de Sitter space
Garriga Torres, Jaume
Universitat de Barcelona
We use the method of Bogolubov transformations to compute the rate of pair production by an electric field in (1+1)-dimensional de Sitter space. The results are in agreement with those obtained previously using the instanton methods. This is true even when the size of the instanton is comparable to the size of the de Sitter horizon.
