Single chain polyelectrolyte conformation 1: Influence of the spatial dimension and ionic strength

Single polyelectrolyte chains were simulated in the Debye-Huckel approximation. The average end-to-end quadratic distance 〈R2〉 was calculated as a function of the chain length, the ionic strength of the solution and the dimension of space. The upper critical dimension d = 6, for the electrostatic in...
