Representing Structural Information of Helical Charge Distributions in Cylindrical Coordinates
arXiv:cond-mat/9612194 · doi:10.1103/PhysRevE.55.3765
Abstract
Structural information in the local electric field produced by helical charge distributions, such as dissolved DNA, is revealed in a straightforward manner employing cylindrical coordinates. Comparison of structure factors derived in terms of cylindrical and helical coordinates is made. A simple coordinate transformation serves to relate the Green function in cylindrical and helical coordinates. We also compare the electric field on the central axis of a single helix as calculated in both systems.
