Unruh Effect |
In General
> s.a. black-hole radiation; entanglement phenomenology
[non-inertial frames]; particle effects [self-energy]; radiation.
* Idea: Radiation seen
by accelerated detectors (e.g., at rest near a black hole, or Rindler
detectors in Minkowski spacetime); An accelerated system heats up, and
responds to inertial vacuum fluctuations as if it was immersed in a thermal
bath of temperature T = (2π\(\hbar\)/ck) a.

* Proposed tests:
It is not easy to realize an experiment whose output could be directly
interpreted in terms of the Unruh effect because the linear acceleration
needed to reach a temperature 1 K is of order \(10^{20}\ {\rm m/s}^2\).
* Anti-Unruh effect: An
effect in which a uniformly accelerated particle detector coupled to
the vacuum cools down as its acceleration increases;
