Experimental Observation of The Unruh Effect
Under experimentally achievable conditions for gravitational systems this effect is too small and its observation is very difficult. It was shown by Bell and Leinaas that if one takes an accelerated observer to be an electron circularly orbiting in a constant external magnetic field, then the experimentally verified Sokolov–Ternov effect coincides with the Unruh effect.
A recent work by Martín-Martínez, Fuentes and Mann showed that accelerated detectors acquire a geometrical phase due to their movement through spacetime and that this can be used for the direct detection of the Unruh effect in regimes physically accessible with current technology.

Famous quotes containing the words experimental, observation and/or effect:
“Whenever a man acts purposively, he acts under a belief in some experimental phenomenon. Consequently, the sum of the experimental phenomena that a proposition implies makes up its entire bearing upon human conduct.”
—Charles Sanders Peirce (1839–1914)
“I should say that the most prominent scientific men of our country, and perhaps of this age, are either serving the arts and not pure science, or are performing faithful but quite subordinate labors in particular departments. They make no steady and systematic approaches to the central fact.... There is wanting constant and accurate observation with enough of theory to direct and discipline it. But, above all, there is wanting genius.”
—Henry David Thoreau (1817–1862)
“Because just as arms have no force outside if there is no counsel within a house, study is vain and counsel useless that is not put to virtuous effect when the time calls.”
—François Rabelais (1494–1553)
