Many-Electron Dynamics of Heavy Atoms in Intense Laser Fields. Effects of Screening and Correlation
In this talk we shall discuss the role of collective effects in multiphoton-multielectron ionization of heavy atoms. In recent work /1,2/ we have developed a theoretical description of multiphoton ionization which takes into account effects of many-electron screening and introduces an effective laser intensity. This is accomplished by introducing a RPA-type of dynamically screened electron-photon coupling. Since every electron-photon interaction operator is screened, our approach includes multiply excited intermediate levels and provides a description of dynamic non-linear response.
