  title={Coulomb Systems at Low Density: A Review},
  author={David Brydges and Ph. A. Martin},
  journal={Journal of Statistical Physics},
Results on the correlations of low-density classical and quantum Coulomb systems at equilibrium in three dimensions are reviewed. The exponential decay of particle correlations in the classical Coulomb system, Debye–Hückel screening, is compared and contrasted with the quantum case, where strong arguments are presented for the absence of exponential screening. Results and techniques for detailed calculations that determine the asymptotic decay of correlations for quantum systems are discussed… 
Quantum Coulomb systems : screening, recombination and van der Waals forces
The study of quantum Coulomb systems at equilibrium is important for understanding properties of matter in many physical situations. Screening, recombination and van der Waals forces are basic
Finite-Size Corrections for Coulomb Systems in the Debye-Huckel Regime
It has been argued that for a finite two-dimensional classical Coulomb system of characteristic size R, in its conducting phase, as R → ∞ the total free energy (times the inverse temperature β)
Equilibrium correlations in charged fluids coupled to the radiation field.
We provide an exact microscopic statistical treatment of particle and field correlations in a system of quantum charges in equilibrium with a classical radiation field. Using the Feynman-Kac-Itô
Quantum Mayer Graphs for Coulomb Systems and the Analog of the Debye Potential
Within the Feynman–Kac path integral representation, the equilibrium quantities of a quantum plasma can be represented by Mayer graphs. The well known Coulomb divergencies that appear in these series
The two-dimensional Coulomb plasma: quasi-free approximation and central limit theorem
For the two-dimensional one-component Coulomb plasma, we derive an asymptotic expansion of the free energy up to order $N$, the number of particles of the gas, with an effective error bound

This paper concerns the equilibrium bulk charge and current density correlation functions in quantum media, conductors and dielectrics, fully coupled to the radiation (the retarded regime). A
Quantum screened interactions in moderately dense plasmas and atomic contributions to thermodynamics
The screened Coulomb interaction φ through which particles interact in the path integral description of quantum plasmas is studied analytically and numerically. This interaction, which is a key
Screened activity expansion for the grand potential of a quantum plasma and how to derive approximate equations of state compatible with electroneutrality.
How the activity series for the pressure, combined with the Debye-dressing prescription, can be used for deriving approximate equations of state at moderate densities, which include the contributions of recombined entities made with three or more particles.


We give the exact low-density coefficients of the large-distance algebraic tails of static correlations in quantum plasmas. Quantum statistics is taken into account, and the interaction is the pure
Exact low-density free energy and algebraic tails of static correlations in quantum plasmas in a uniform magnetic field
In nonrelativistic Coulomb plasmas with quantum dynamics and statistics, the effect of an external uniform magnetic field upon thermodynamics and the algebraic tails of position correlations is

The existence and exponential clustering of correlation functions for a dilute classical coulomb system are proven using methods from constructive quantum field theory, the sine gordon transformation

A detailed, rigorous study of the statistical mechanics-screening- and critical properties, phase diagrams, etc., of classical Coulomb monopole and dipole gases in two or more dimensions is
Coulomb systems seen as critical systems: Finite-size effects in two dimensions
It is known that the free energy at criticality of a finite two-dimensional system of characteristic sizeL has in general a term which behaves like logL asL→∞; the coefficient of this term is
Mean field theory for Coulomb systems
We study a classical charge symmetric system with an external charge distributionq in three dimensions in the limit that the plasma parameter ɛ→ zero. We prove that ifq is scaled appropriately then
Absence of Exponential Clustering for the Static Quantum Correlations and the Time-Displaced Correlations in Charged Fluids
The 4-term in the Wigner-Kirkwood expansion of the equilibrium charge-charge correlations of a quantum one-component plasma (OCP) is found to decay like 1/r10. The t8-term in the small time expansion

A term-by-term diagrammatic proof is given by using the formalism of paper I, where the quantum particle-particle correlations are expressed in terms of classical-loop distribution functions, which reflects the fact that the charge-charge or multipole-charge interactions between clusters of particles surrounded by their polarization clouds are exponentially screened.
