Flavor mixing transformations for a uniformly accelerated observer

[摘要] We study flavor mixing transformations for a uniformly accelerated observer (Rindler observer) in the simplest case of two charged scalar fields with different masses. This is obtained starting from an analysis of boson field mixing in inertial frame (Minkowski frame) in the hyperbolic basis. As a consequence of the non-trivial interplay between the Bogolubov transformation related to flavor mixing and the one arising from the Rindler spacetime structure, the Fulling-Rindler condensate of the inertial vacuum gets deeply modified, losing its original thermal nature.
