%0 Journal Article %T Nucleus Driven Electronic Pulsation %A H. Ludwig %A R. Ruffini %A S. -S. Xue %J Physics %D 2014 %I arXiv %X We derive and solve by the spectral method the equations for a neutral system of ultra-relativistic electrons that are compressed to the radius of the nucleus and subject to a driving force. This driving force can be thought of as originating from a nuclear breathing mode, a possibility we discuss in detail. %U http://arxiv.org/abs/1412.5455v1
