| Popis: | In the very early universe, a generalized Schwinger effect can create pairs from both electrical and gravitational fields. The expectation value of fermionic current induced by these newly created pairs has been recently computed in de Sitter spacetime. I will discuss different limiting cases of this result and some of its possible physical interpretations. Comment: 9 pages, 1 figure, to appear in the Proceedings of the Marcel Grossmann meeting 2015 |
