Simulations of noise in disordered systems
- Charles
- Cynthia J.
We use particle dynamics simulations to probe the correlations between noise and dynamics in a variety of disordered systems, including super conducting vortices, 2D electron liquid crystals, colloids, domain walls, and granular media. The noise measurements offer an experimentally accessible link to the microscopic dynamics, such as plastic versus elastic flow during transport, and can provide a signature of dynamical reordering transitions in the system. We consider broad and narrow band noise in transport systems, as well as the fluctuations of dislocation density in a system near the melting transition.
