Dynamics of Nonlinear Lattices
Christopher Chong, P. G. Kevrekidis
In this topical review we explore the dynamics of nonlinear lattices with a particular focus to Fermi-Pasta-Ulam-Tsingou type models that arise in the study of elastic media and, m…

Modulation Instability and Wavenumber Bandgap Breathers in a Time Layered Phononic Lattice
Christopher Chong, Brian Kim, Evelyn Wallace +1
We demonstrate the existence of wavenumber bandgap (q-gap) breathers in a time-periodic phononic lattice. These breathers are localized in time and periodic in space, and are the c…

Time- and space-variant wave transmission in helicoidal phononic crystals
F. Li, C. Chong, J. Yang +2
We present a dynamically tunable mechanism of wave transmission in 1D helicoidal phononic crystals in a shape similar to DNA structures. These helicoidal architectures allow slante…
