Screening in Yukawa fluid mixtures | | A.J. Archer

28 Jun 2006 | | Subject: | Soft Condensed Matter; Statistical Mechanics | | Abstract: | The effective pair potential between mesoscopic charged particles in a neutralising background medium takes a Yukawa form $exp(-lambda r)/r$ with screening length $lambda^{-1}$. We consider a dilute suspension of such Yukawa particles dispersed in a solvent with correlation length $xi<lambda^{-1}$ and show that the Yukawa interaction is `screened’ if the pair potentials between solvent particles exhibit Yukawa decay with the same screening length $lambda^{-1}$. However, if the solvent pair potentials are shorter ranged than the solute Yukawa potentials, then the effective potential between pairs of solute particles is `unscreened’, i.e. the effective potential between the solute particles is equal to the bare potential at large particle separations. | | Source: | arXiv, cond-mat/0606718 | | Services: | Forum | Review | PDF | Favorites | |
