【 摘 要 】

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.
