... in the element. It is just a simple decay from an excited to a lower (ground) state. In the process of course some energy is released that is carried away by a photon. Similar processes occur in atomic physics, however there the energy changes are usually much smaller, and photons that emerge are in ...

On the radiation by a charge in a material medium
... charge is studied is the analysis of the effects produced by the radiated fields on its source, that is, the radiation reaction. Hence it is interesting to discuss the dynamical effects on a charge due to the emission of Cherenkov radiation. In the present work we make explicit and thoroughly develo ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
