Coulomb interactions between disordered charge distributions
David S. Dean, Ali Naji, Ronald R. Horgan +2
We review some of the recent results in the context of the Coulomb interaction between dielectric surfaces which are randomly charged but remain net-neutral on the average. Such su…
Wrapping Transition and Wrapping-Mediated Interactions for Discrete Binding along an Elastic Filament: An Exact Solution
David S. Dean, Thomas C. Hammant, Ronald R. Horgan +2
The wrapping equilibria of one and two adsorbing cylinders are studied along a semi-flexible filament (polymer) due to the interplay between elastic rigidity and short-range adhesi…
The one dimensional Coulomb lattice fluid capacitor
Vincent Demery, David S. Dean, Thomas C. Hammant +2
The one dimensional Coulomb lattice fluid in a capacitor configuration is studied. The model is formally exactly soluble via a transfer operator method within a field theoretic rep…
Non-monotoic fluctuation-induced interactions between dielectric slabs carrying charge disorder
Jalal Sarabadani, Ali Naji, David S. Dean +2
We investigate the effect of monopolar charge disorder on the classical fluctuation-induced interactions between randomly charged net-neutral dielectric slabs and discuss various g…
Path integrals for stiff polymers applied to membrane physics
D. S. Dean, R. R. Horgan
Path integrals similar to those describing stiff polymers arise in the Helfrich model for membranes. We show how these types of path integrals can be evaluated and apply our result…
Some observations on the renormalization of membrane rigidity by long-range interactions
D. S. Dean, R. R. Horgan
We consider the renormalization of the bending and Gaussian rigidity of model membranes induced by long-range interactions between the components making up the membrane. In particu…
The field theory of symmetrical layered electrolytic systems and the thermal Casimir effect
D. S. Dean, R. R. Horgan
We present a general extension of a field-theoretic approach developed in earlier papers to the calculation of the free energy of symmetrically layered electrolytic systems which i…
The thermal Casimir effect in lipid bilayer tubules
D. S. Dean, R. R. Horgan
We calculate the thermal Casimir effect for a dielectric tube of radius and thickness delta formed from a membrane in water. The method uses a field-theoretic approach in the g…
The two loop calculation of the disjoining pressure of a symmetric electrolyte soap film
D. S. Dean, R. R. Horgan
In this paper we consider the two-loop calculation of the disjoining pressure of a symmetric electrolytic soap film. We show that the disjoining pressure is finite when the loop ex…
Field theoretic calculation of the surface tension for a model electrolyte system
D. S. Dean, R. R. Horgan
We carry out the calculation of the surface tension for a model electrolyte to first order in a cumulant expansion about a free field theory equivalent to the Debye-Hückel approxim…
The field theoretic derivation of the contact value theorem in planar geometries and its modification by the Casimir effect
D. S. Dean, R. R. Horgan
The contact value theorem for Coulomb gases in planar or film-like geometries is derived using a Hamiltonian field theoretic representation of the system. The case where the film i…
Weak non-linear surface charging effects in electrolytic films
D. S. Dean, R. R. Horgan
A simple model of soap films with nonionic surfactants stabilized by added electrolyte is studied. The model exhibits charge regularization due to the incorporation of a physical m…
