Does the Unruh effect need the accelerating observer's Hilbert space to be smaller than the inertial one?

I've encounter two different approaches to the Unruh effect and I feel like they are not consistent with one another. Bogoliubov Transformation In this approach the basic statement is that the vacuum ...

Flux and radiation pressure from Unruh radiation?

A collection of accepted answers on Physics Exchange paint a seemingly inconsistent picture of Unruh radiation and it's isotropy. One of the most sophisticated answers, from Lubosz Motl, to the ...

How does the Unruh effect create particles?

I've read that the Rindler horizon cuts off access to fundamental quantum fields and leads to a mixing of positive and negative frequencies via the Bogoliubov transformations. But here is where I have ...

Ways to derive black-body radiation in Unruh effect

I know two ways to derive black-body radiation in Unruh effect and they are: Using Bogoliubov coefficients (N. D. Birrell and Paul Davies) Using Page approximation (David J. Toms and Leonard Parker) ...
