Violation of the equivalence principle via the Unruh effect

ORAL

Abstract

We show that in certain situations the equivalence principle - stated as the local equality of acceleration with a gravitational field - is violated by the Unruh effect. For a black hole space-time with a horizon the EP holds, while for a gravitating body without a horizon (e.g. the Earth, a white dwarf, a neutron star) the EP is violated.
