The sound speed in Yukawa one component plasmas across coupling regimes
Luciano G Silvestri, Gabor J. Kalman, Zoltán Donkó +4
A many-body system of charged particles interacting via a pairwise Yukawa potential, the so-called Yukawa One Component Plasma (YOCP) is a good approximation for a variety of physi…
Is the Vlasov equation valid for Yukawa plasmas?
Kenneth I. Golden, Gabor J. Kalman, Luciano G. Silvestri
We analyze the Vlasov dispersion relation for Yukawa plasmas in three dimensions for the purpose of identifying coupling parameter domains where the Vlasov approach is justified an…
Correlation induced out-of-phase plasmon in an electron liquid
Gabor J. Kalman, Kenneth I. Golden, Luciano G. Silvestri
We derive from first principles the existence of a low-frequency plasmon in a strongly coupled three-dimensional homogeneous electron gas (HEG). From its dispersion and its satisfa…
Factorization of 3-point static structure functions in 3D Yukawa liquids
Peter Magyar, Peter Hartmann, Gabor J. Kalman +2
In many-body systems the convolution approximation states that the 3-point static structure function, , can approximately be "factorized" in…
Hierarchy of Fluctuation-Dissipation Theorems for the Classical One-Component Plasma
Kenneth Golden, Joshuah Heath
We have derived tractable cubic (p=3) and quartic (p=4) fluctuation-dissipation theorems (FDTs) for the classical one-component plasma in a form that links a single (p+1)-point dyn…
Second Plasmon and Collective Modes in Binary Coulomb Systems
Gabor J. Kalman, Zoltan Donko, Peter Hartmann +1
In a system consisting of two different charged species we identify the excitation of a second, low frequency plasmon. At strong coupling the doublet of high frequency (first) and…
