Hello everybody,

I am currently studying QFT on curved spacetime and I got puzzled about the question:

Are Unruh and Hawking effect just the same by invoking the equivalence principle?

I found ambiguous statements and this paper contributed to it. http://arxiv.org/pdf/1102.5564v2.pdf

Is anybody here who knows details, can refer any good paper, argumentation?

Thanks in advance!

It is widely agreed that they are different (but in many respects similar) effects, and the paper you mention confirms it.

By the way, I have another question which someone might be able to answer. There are many examples of condensed-matter ANALOGUE Hawking radiation, but is there a similar ANALOGUE Unruh effect?
 
Thanks Demystifier,
but in which precise aspects are they different and in which similar? Is there a clear analysis somewhere available?
 
A lot of the 'differences' seem related to different frames of reference...

We had a rather good discussion here:

with some interesting links.

And Wikipedia offers this:

..The Rindler spacetime has a horizon, and locally any non-extremal black hole horizon is Rindler. So the Rindler spacetime gives the local properties of black holes and cosmological horizons. The Unruh effect would then be the near-horizon form of the Hawking radiation.

Some connections between Unruh and Hawking effects are mentioned here:

I seem to notice a buildup of papers like this: Detecting single gravitons with quantum sensing. (OK, old one.) Toward graviton detection via photon-graviton quantum state conversion Is this akin to “we’re soon gonna put string theory to the test”, or are these legit? Mind, I’m not expecting anyone to read the papers and explain them to me, but if one of you educated people already have an opinion I’d like to hear it. If not please ignore me. EDIT: I strongly suspect it’s bunk but...
