Spontaneous excitation of an accelerated hydrogen atom coupled with electromagnetic vacuum fluctuations

摘要: We consider a multilevel hydrogen atom in interaction with the quantum electromagnetic field and separately calculate contributions of vacuum fluctuation radiation reaction to rate change mean atomic energy for uniform acceleration. It is found that acceleration disturbs fluctuations such way delicate balance between exists inertial atoms broken, so transitions higher-lying states from ground state are possible even vacuum. In contrast case an interacting scalar field, both spontaneous emission affected by acceleration, furthermore contribution contains nonthermal acceleration-dependent correction, which possibly observable.
