Lyapunov exponents explain disorder-induced polarization and soliton teleportation in a mechanical Markov system
Will Stephenson, Nan Cheng, Kai Sun +1
Using a mapping between spatial disorder and temporal stochasticity, we develop a new framework using Lyapunov exponents to explain exotic wave localization and mobility phenomena…

Observation of mechanical kink control and generation via phonons
Kai Qian, Nan Cheng, Francesco Serafin +4
Kinks (or domain walls) are localized transitions between distinct ground states associated with a topological invariant, and are central to many phenomena across physics, from con…
