Abstract:

Virtual processes are part of the vacuum picture of quantum electrodynamics. They result in spontaneous creation of particles in external fields or curved space-times. Ground-state atoms, accelerated through vacuum, will be promoted to an excited state by emitting a photon. This is known as Unruh acceleration radiation. I will discuss physics of the acceleration radiation and excitation of an atom by a uniformly accelerated mirror. The latter is similar to radiation of atom freely falling in gravitational field of a black hole which is manifestation of the Einstein equivalence principle.
