Integrable Approximations of Dispersive Shock Waves of the Granular Chain

C. Chong, A. Geisler, P. G. Kevrekidis +1

In the present work we revisit the shock wave dynamics in a granular chain with precompression. By approximating the model by an $\alpha$-Fermi-Pasta-Ulam-Tsingou chain, we leverage the…
