Stripes, Clusters, and Nonequilibrium Ordering for Bidisperse Colloids with Repulsive Interactions
C. Reichhardt, C. J. Olson Reichhardt
We show that two-dimensional bidisperse assemblies of colloids with strictly repulsive interactions exhibit stripe, cluster, and partially crystallized states when driven over a qu…
Electrophoresis of DNA on a disordered two-dimensional substrate
C. J. Olson Reichhardt, C. Reichhardt
We propose a new method for electrophoretic separation of DNA in which adsorbed polymers are driven over a disordered two-dimensional substrate which contains attractive sites for…
Reentrant Disordering of Colloidal Molecular Crystals on 2D Periodic Substrates
M. Mikulis, C. J. Olson Reichhardt, C. Reichhardt +2
We study colloidal ordering and disordering on two-dimensional periodic substrates where the number of colloids per substrate minima is two or three. The colloids form dimer or tri…
Directional Locking Effects and Dynamics for Particles Driven Through a Colloidal Lattice
C. Reichhardt, C. J. Olson Reichhardt
We examine the dynamics of a single colloidal particle driven through a colloidal lattice which can distort in response to the driven particle. We find a remarkably rich variety of…
Spontaneous Symmetry Breaking for Driven Interacting Particles on Triangular Substrates
C. Reichhardt, C. J. Olson Reichhardt
For collectively interacting repulsive particles driven on triangular substrates, we show that for certain directions of drive a spontaneous symmetry breaking phenomena occurs wher…
Frustration and Melting of Colloidal Molecular Crystals
C. J. Olson Reichhardt, C. Reichhardt
Using numerical simulations we show that a variety of novel colloidal crystalline states and multi-step melting phenomena occur on square and triangular two-dimensional periodic su…
