Simulational study of anomalous tracer diffusion in hydrogels
Fatemeh Tabatabaei, Olaf Lenz, Christian Holm
In this article, we analyze different factors that affect the diffusion behavior of small tracer particles (as they are used e.g.in fluorescence correlation spectroscopy (FCS)) in…
P3M algorithm for dipolar interactions
Juan J. Cerda, V. Ballenegger, O. Lenz +1
An extension to the P3M algorithm for electrostatic interactions is presented, that allows to efficiently compute dipolar interactions in periodic boundary conditions. Theoretical…
Simulation of charge reversal in salty environments: Giant overcharging?
Olaf Lenz, Christian Holm
We have performed MD simulations of a highly charged colloid in a solution of 3:1 and additional 1:1 salt. The dependency of the colloid's inverted charge on the concentration of t…
The optimal P3M algorithm for computing electrostatic energies in periodic systems
V. Ballenegger, J. J. Cerda, Ch. Holm +1
We optimize Hockney and Eastwood's Particle-Particle Particle-Mesh (P3M) algorithm to achieve maximal accuracy in the electrostatic energies (instead of forces) in 3D periodic char…
A generic model for lipid monolayers, bilayers, and membranes
F. Schmid, D. Duchs, O. Lenz +1
We describe a simple coarse-grained model which is suited to study lipid layers and their phase transitions. Lipids are modeled by short semiflexible chains of beads with a solvoph…
Structure of symmetric and asymmetric "ripple" phases in lipid bilayers
Olaf Lenz, Friederike Schmid
We reproduce the symmetric and asymmetric ``rippled'' states of lipid membranes by Monte Carlo simulations of a coarse-grained molecular model for lipid-solvent mixtures.…
