We study the mixing of two complex boson fields with different masses in Rindler spacetime. We find that the Bogoliubov transformation associated with field mixing combines in a non-trivial way with the thermal Bogoliubov transformation associated to the uniformly accelerated observer (Rindler observer): as a result, the spectrum of Unruh radiation gets modified.

Abstract
We study the mixing of two complex boson fields with different masses in Rindler spacetime. We find that the Bogoliubov transformation associated with field mixing combines in a non-trivial way with the thermal Bogoliubov transformation associated to the uniformly accelerated observer (Rindler observer): as a result, the spectrum of Unruh radiation gets modified.File in questo prodotto:
