Surface Effects in Debye Screening*
A thermodynamic system of equally charged, plus and minus, classical particles constrained to move in a (spherical) ball is studied in a region of parameters in which Debye screening takes place. The activities of the two charge species are not taken as necessarily equal. We must deal with two physically interesting surface effects, the formation of a surface charge layer, and long range forces...
متن کاملDebye Screening in the Qcd Plasma
Various definitions for the QCD Debye mass and its evaluation are reviewed in a non-perturabtive framework for the study of screening of general static sources. While it is possible to perturbatively integrate over scales ∼ T and thus construct a 3d effective theory, the softer scales ∼ gT and ∼ gT are strongly coupled for temperatures < ∼ 10 GeV and require lattice simulations. Within the effe...
متن کاملDebye Screening at Finite Temperature , Revisited ∗ )
We present an alternative way to calculate the screening of the static potential between two charges in (non)abelian gauge theories at high temperatures. Instead of a loop expansion of a gauge boson self-energy, we evaluate the energy shift of the vacuum to order e 2 after applying an external static magnetic field and extract a temperature-and momentum-dependent dielectric permittivity. The Ha...
متن کاملAbsence of Debye Screening in the QuantumCoulomb
We present an approximation to the quantum Coulomb plasma at equilibrium which captures the power-law violations of Debye screening which have been reported in recent papers. The objectives are: (1) to produce a simpler model which we will study in forthcoming papers, (2) to develop a strategy by which the absence of screening can be proven for the low density quantum Coulomb plasma itself. 1 T...
متن کاملNonabelian Debye Screening, Tsunami Waves, and Worldline Fermions
I give a pedagogical review of the derivation for the effective lagrangian for nonabelian Debye screening, or hard thermal loops. Following Kelly, Liu, Lucchesi, and Manuel, I give the simplest derivation possible, using classical kinetic theory. The result is valid not just for a thermal, but for an arbitrary initial distributions. I use this to study the evolution, at short times, of a gluoni...
