Quantum theory of correlation functions for liquid metals and normal liquids in the zero sound wave range

摘要: Abstract The correlation functions of liquid metals and normal liquids in the zero sound wave range are formulated using quantum-mechanical two-time Green function method, classical formula Bogolyubov-Sadovnikov Nelkin-Ranganathan for is extended to case. obtained clarifies relation between coherent-correlation self-correlation a free gas, becomes extension Kerr's relation. effective potential classically by Percus Zwanzig from direct case, S ( k, E ) obtained. ions taking into account contribution conduction electrons. And March improved electron effect together with exchange interaction.
