Failure of the Goldstone Theorem for Vector Fields and Boundary-Mode Proliferation in Hyperbolic Lattices
Daniel Sela, Nan Cheng, Kai Sun
Hyperbolic lattices extend crystallinity into curved space, where negative curvature and exponentially large boundaries reshape collective excitations beyond Euclidean intuition. I…

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…
