Structure and dynamics of two-dimensional colloidal systems in circular cavities

In addition, we determine the effect of pinned particles on their local environment, and their correlation to critical fluctuations close to the phase transitions.. Another way

(a) For G ¼ 12.8 the large and small particles are rather well located, (b) for G ¼ 8.7 the larger particle are rather fixed but the small ones can still diffuse in the matrix of

Using positional data from videomicroscopy and applying the equipartition theorem for harmonic Hamiltonians, we determine the wave-vector-dependent normal mode spring constants of

Since melting in 2D is closely connected with the dissociation of dislocation pairs (two 5-fold and two 7- fold coordinated particles) into free dislocations (a 5-fold and a

enhanced by high density. While the intensity cutoff in the tracking algorithm can be chosen low enough to ensure continuous particle detection, every calculation of quan-

[TMBZ98], is also an elegant way to determine the potential depth of the single trap and the laser intensity in the focus from the mean angular velocity v P of a single,

The mixture exhibits a partial clustering in equilibrium: in the voids of the matrix of unclustered big particles, the small particles form subclusters with a spongelike topology

However, while due to symmetry the particles in the 2/3 structure are fixed to the centers of their lattice sites, the empty sites constituting the domain walls allow the clusters in
