Radiating Solitary Waves in an FPUT Lattice with Random Coefficients

Hermen Jan Hupkes, Joshua A. McGinnis, Rik W. S. Westdorp +1

We study the propagation of solitary waves in a Fermi-Pasta-Ulam-Tsingou (FPUT) lattice with small random heterogeneity in the linear spring force. Perturbed by the random environm…
