Estimating topological entropy from the motion of stirring rods
Sarah E. Tumasz, Jean-Luc Thiffeault
Stirring a two-dimensional viscous fluid with rods is often an effective way to mix. The topological features of periodic rod motions give a lower bound on the topological entropy…
Topological entropy and secondary folding
Sarah Tumasz, Jean-Luc Thiffeault
A convenient measure of a map or flow's chaotic action is the topological entropy. In many cases, the entropy has a homological origin: it is forced by the topology of the space. F…
Trajectory entanglement in dense granular materials
James G. Puckett, Frédéric Lechenault, Karen E. Daniels +1
The particle-scale dynamics of granular materials have commonly been characterized by the self-diffusion coefficient . However, this measure discards the collective and topologi…
