Electrostatic interactions between discrete helices of charge (2009)
Landy, Jonathan, Rudnick, Joseph
We analytically examine the pair interaction for parallel, discrete helices of charge. Symmetry arguments allow for the energy to be decomposed into a sum of terms, each of which has an intuitive...
Modulation effects within the mean-field theory of electrolyte solutions (2009)
The consequences of source charge and surface modulation are studied within the framework of the Poisson-Boltzmann theory of electrolyte solutions. Through a consideration of various examples, it is...
Fourier expansions for the potentials of lattices of charge (2008)
We apply the Poisson sum rule to obtain formal expressions for the Fourier coefficients of the potential of a lattice of generalized charge. Each generalized charge is assumed to contribute to the...
Centred approach to the period of anharmonic oscillators (2007)
We present a simple method for obtaining a concise series expression for the period of one-dimensional classical oscillators. The series converges well for typical potentials and is of a form that is...
