Near critical electrolytes: Are the charge-charge sum rules obeyed?

Journal of Chemical Physics, 2012
In an electrolyte solution the charge-charge structure factor obeys $S_{ZZ}(k;T,\rho )=0+\xi _{Z,1}^2k^2\break -\xi _{Z,2}^4k^4+\cdots$SZZ(k;T,ρ)=0+ξZ,12k2−ξZ,24k4+⋯ , where ξZ, 1 and ξZ, 2 are the second- and fourth-moment charge-charge correlation lengths depending on the temperature T and the overall ion density ρ. The vanishing of the leading term,

Theory to determine the critical charge density

IEEE Transactions on Dielectrics and Electrical Insulation, 1998
In this paper we determine theoretically the critical charge density in the system grounded metallic sphere, uniformly charged dielectric plane, in the presence of grounded surfaces. This is a situation frequently encountered in industrial condition and is important in evaluating the danger of the electrostatic discharges.

Quantum defects at the critical charge

The Journal of Chemical Physics, 2013
The quantum defect is an empirically introduced notion that has allowed convenient interpolations of spectral data along atomic isoelectronic sequences and their extrapolation with respect to the principal quantum number. Both yield valuable spectral information, the latter providing estimates of low-energy-electron elastic scattering phase shifts as ...

Quantum Critical Phenomena in Charged Superconductors

Physical Review Letters, 1988
We study the effect of Coulomb interactions on the onset of superconductivity with increasing intergrain coupling in granular systems at $T=0$. We show that in three dimensions (3D) the onset transition is described by Euclidean scalar electrodynamics, and so can be either first or second order, depending on parameters. A renormalization-group analysis
