A Quantum Fluid Description of the Free Electron Laser
arXiv:0810.4025 · doi:10.1103/PhysRevA.79.015801
Abstract
Using the Madelung transformation we show that in a quantum Free Electron Laser (QFEL) the beam obeys the equations of a quantum fluid in which the potential is the classical potential plus a quantum potential. The classical limit is shown explicitly.
