Fermionic Current and Schwinger Effect in De Sitter spacetime |
|
Abstract |
I will show how to derive the fermionic current induced by a constant electric field in 1+1 dimensional de Sitter spacetime. To do this positive and negative energy solutions of the Dirac equation in curved spacetime are constructed. The current calculated with the help of this solutions is then regularized using adiabatic subtraction. The physical implications of this result will be discussed in depth in the presentation of Clément Stahl. |
