Abstract
The electromagnetic field is canonically quantized in the presence of a linear, dispersive, and dissipative medium that is in uniform motion. Specifically we calculate the change in the normal modes of the coupled matter-field system and find a Hamiltonian that contains negative-energy normal modes. We interpret these modes as the origin of phenomena such as quantum friction and find that a detector initially in its ground state and coupled to the electromagnetic field in the vicinity of, or within, a uniformly moving medium has a nonzero probability of excitation at K.
