Reversible to Irreversible Flow Transition in Periodically Driven Vortices
N. Mangan, C. Reichhardt, C. J. Olson Reichhardt
We show that periodically driven superconducting vortices in the presence of quenched disorder exhibit a transition from reversible to irreversible flow under increasing vortex den…
Enhancing Mixing and Diffusion with Plastic Flow
A. Libal, C. Reichhardt, C. J. Olson Reichhardt
We use numerical simulations to examine two-dimensional particle mixtures that strongly phase separate in equilibrium. When the system is externally driven in the presence of quenc…
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…
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…
Nonlinear dynamics, rectification, and phase locking for particles on symmetrical two-dimensional periodic substrates with dc and circular ac drives
C. Reichhardt, C. J. Olson Reichhardt, M. B. Hastings
We investigate the dynamical motion of particles on a two-dimensional symmetric periodic substrate in the presence of both a dc drive along a symmetry direction of the periodic sub…
Absolute Transverse Mobility and Ratchet Effect on Periodic 2D Symmetric Substrates
C. Reichhardt, C. J. Olson Reichhardt
We present a simple model of an overdamped particle moving on a two dimensional symmetric periodic substrate with a dc drive in the longitudinal direction and additional ac drives…
