Unruh effect should work for any acceleration, including centripetal acceleration of a James Bond-style killer centrifuge/amusement ride. The "thermal bath" experienced by such an observer is composed mainly of photons, but also some elementary particles, in proportion to quantum field coupling strengths or something, coming in as a "particle shower" from the direction of the Rindler event horizon - namely down. The accelerated observer can capture these particles for use later. Did I get it all correct?
good meme!
by the equivalence principle, even earth's 1g gravitational field should already lead to some Unruh radiation for us, so you don't even need a centrifuge!
but your centrifuge is interesting. from the PoV of someone at rest angular momentum needs to be conserved so as you get fatter the rotation must slow down as @herrpfad@feddit.org said. but from the troll's PoV why should they slow down? it's a thermal spectrum, and acceleration is radially inward, so why should there be a retrograde force? (like, what makes the retrograde direction more special then prograde?)
i think the resolution is you don't get exactly Unruh radiation (because your acceleration isn't actually constant (its rotating)), but how exactly that affects the mode functions i have no idea
also let's tag @surrealpartisan@lemmy.world
Ooh, thanks for the tag! This is great!
