Nanoptera in nonlinear woodpile chains with zero precompression
Guo Deng, Christopher J. Lustri
We use exponential asymptotics to study travelling waves in woodpile systems modelled as singularly perturbed granular chains with zero precompression and small mass ratio. These s…

Nanoptera in weakly nonlinear woodpile and diatomic granular chains
Guo Deng, Christopher J. Lustri, Mason A. Porter
We study ``nanoptera'', which are non-localized solitary waves with exponentially small but non-decaying oscillations, in two singularly-perturbed Hertzian chains with precompressi…
