Structure and Fragmentation in Colloidal Artificial Molecules and Nuclei
C. J. Olson Reichhardt, C. Reichhardt, A. R. Bishop
Motivated by recent experiments on colloidal systems with competing attractive and repulsive interactions, we simulate a two-dimensional system of colloids with competing interacti…
Defect Fluctuations and Lifetimes in Disordered Yukawa Systems
C. Reichhardt, C. J. Olson Reichhardt
We examine the time dependent defect fluctuations and lifetimes for a bidisperse disordered assembly of Yukawa particles. At high temperatures, the noise spectrum of fluctuations i…
Cooperative Behavior and Pattern Formation in Mixtures of Driven and Nondriven Colloidal Assemblies
C. Reichhardt, C. J. Olson Reichhardt
We simulate a disordered assembly of particles interacting through a repulsive Yukawa potential with a small fraction of the particles coupled to an external drive. Distortions in…
Heterogeneities and Topological Defects in Two-Dimensional Pinned Liquids
J. -X. Lin, C. Reichhardt, Z. Nussinov +2
We simulate a model of repulsively interacting colloids on a commensurate two-dimensional triangular pinning substrate where the amount of heterogeneous motion that appears at melt…
Ratchet Effect and Nonlinear Transport for Particles on Random Substrates with Crossed ac Drives
C. Reichhardt, C. J. Olson Reichhardt
We show in simulations that overdamped interacting particles in two dimensions with a randomly disordered substrate can exhibit novel nonequilibrium transport phenomena including a…
Coarsening of Topological Defects in Oscillating Systems with Quenched Disorder
C. Reichhardt, C. J. Olson Reichhardt
We use large scale simulations to study interacting particles in two dimensions in the presence of both an ac drive and quenched disorder. As a function of ac amplitude, there is a…
