Frank's constant in the hexatic phase
P. Keim, G. Maret, H. H. von Gruenberg
Using video-microscopy data of a two-dimensional colloidal system the bond-order correlation function G6 is calculated and used to determine the temperature-dependence of both the…
Elastic Behavior of a Two-dimensional Crystal near Melting
H. H. von Grünberg, P. Keim, K. Zahn +1
Using positional data from video-microscopy we determine the elastic moduli of two-dimensional colloidal crystals as a function of temperature. The moduli are extracted from the wa…
Harmonic lattice behavior of two-dimensional colloidal crystals
P. Keim, G. Maret, U. Herz +1
Using positional data from video-microscopy and applying the equipartition theorem for harmonic Hamiltonians, we determine the wave-vector-dependent normal mode spring constants of…
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…
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…
