CANCELLED ! Screened interactions within dense plasmas

Description
Plasma representing the fourth fundamental state of matter is abundant in the universe. Dense plasmas can be found in all types of stars, within giant planets, and are commonly created under laboratory conditions during  experiments involving high-power light sources. In dense plasmas free electrons stay in a close vicinity of ions, affecting their atomic potentials. The ions then cannot  be any longer treated as isolated particles. Correct description of their modified atomic potentials and of the resulting screened interaction rates requires a treatment of the many-body 'plasma screening' effect. In this talk I will discuss various theoretical approaches to describe the screening effect within dense plasmas and their recently available experimental verification.
