## Light front nuclear physics: Toy models, static sources, and tilted light front coordinates

The principles behind the detailed results of a light-front mean field theory of finite nuclei are elucidated by deriving the nucleon mode equation using a simple general argument, based on the idea that a static source in equal time coordinates corresponds to a moving source in light front coordinates. This idea also allows us to solve several simple toy model examples: scalar field in a box, (1+1)-dimensional bag model, three-dimensional harmonic oscillator and the Hulthen potential. The latter provide simplified versions of momentum distributions and form factors of relevance to experiments. In particular, the relativistic correction to the mean squaremore »
