Hi
I'm trying to learn more about the Unruh effect, and was wondering if someone could comment on how exactly the lack of Poincare symmetry in a general curved space leads ambiguity in the notion of "particles".
Why exactly do we associate particles in QFT with positive frequency modes with respect to some preferred time? this idea is not very clear in my mind.
Thanks for any help or links
