Electron Wave Spin in Excited States
Ju Gao, Fang Shen
The wave spin of an electron can be fully characterized by the current density calculated from the exact four-spinor solution of the Dirac equation. In the excited states of the el…
Ponderomotive tunneling in electron-laser interactions
Ju Gao, Fang Shen
It is known that the ponderomotive potential from the laser electron interaction behaves like a static potential that scatters off electrons. We have investigated the process of th…
Classical Field Theory of Cerenkov Radiation Devices
Fang Shen, Ju Gao
The usually continuous and incoherent Cerenkov radiation (CR) is converted into coherent and narrow-band radiation from within a dielectric-line cavity excited by a dc electron bea…
Quantum Properties of Cavity Cerenkov Radiation
Ju Gao, Fang Shen
Cerenkov radiation from cavities have been analyzed by quantum electrodynamic theory. Analytical expressions of some basic radiation properties including Einstein's and coe…
