Friedel sum rule at finite temperature in hot dense plasmas
G. Faussurier, C. Blancard
Abstract
We study the notion of Friedel sum rule at finite temperature in hot dense plasmas. Using the average-atom model, we establish expressions for the Friedel sum rule at zero and finite temperature using non-relativistic or relativistic approaches. Formulas are also given using the Born approximation for the phase shifts. Numerical examples are provided. The Friedel sum rule is a stringent test of the internal consistency of a quantum average-atom model. The question of normalization of free wavefunctions is also discussed.
