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…
Triplet correlations in two-dimensional colloidal model liquids
Carsten Russ, Klaus Zahn, Hans-Hennig von Grunberg
Three-body distribution functions in classical fluids have been theoretically investigated many times, but have never been measured directly. We present experimental three-point co…
Three-Particle Correlations in Simple Liquids
Klaus Zahn, Georg Maret, Carsten Russ +1
We use video microscopy to follow the phase-space trajectory of a two-dimensional colloidal model liquid and calculate three-point correlation functions from the measured particle…
Elastic properties of 2D colloidal crystals from video microscopy
K. Zahn, A. Wille, G. Maret +2
Elastic constants of two-dimensional (2D) colloidal crystals are determined by measuring strain fluctuations induced by Brownian motion of particles. Paramagnetic colloids confined…
