Effect of many-body interactions on the solid-liquid phase-behavior of charge-stabilized colloidal suspensions
J. Dobnikar, R. Rzehak, H. H. von Gruenberg
The solid-liquid phase-diagram of charge-stabilized colloidal suspensions is calculated using a technique that combines a continuous Poisson-Boltzmann description for the microscop…
Stability of gap solitons in a Bose-Einstein condensate
Karen Marie Hilligsoe, Markus K. Oberthaler, Karl-Peter Marzlin
We analyze the dynamical stability of gap solitons formed in a quasi one-dimensional Bose-Einstein condensate in an optical lattice. Using two different numerical methods we show t…
Gaussian ellipsoid model for confined polymer systems
F. Eurich, P. Maass, J. Baschnagel
Polymer systems in slab geometries are studied on the basis of the recently presented Gaussian Ellipsoid Model [J. Chem. Phys. 114, 7655 (2001)].The potential of the confining wall…
Effective medium theory of conduction in stretched polymer electrolytes
Oliver Duerr, Wolfgang Dieterich, Philipp Maas +1
Recent experimental observations of anisotropic conductivity in stretched polymer electrolytes films of the polyethylene oxide family are discussed. The main experimental observati…
The osmotic pressure of charged colloidal suspensions: A unified approach to linearized Poisson-Boltzmann theory
Markus Deserno, Hans-Hennig von Grunberg
We study theoretically the osmotic pressure of a suspension of charged objects (e.g., colloids, polyelectrolytes, clay platelets, etc.) dialyzed against an electrolyte solution usi…
