Coherent structures in long range FPUT lattices, Part I: Solitary Waves
J. Douglas Wright, Udoh Akpan
We consider long range variants of Fermi-Pasta-Ulam-Tsingou lattice and in particular allow for particles to interact over arbitrarily long distances. We develop sufficient conditi…

Mass-in-Mass Lattices with Small Internal Resonators
Fazel Hadadifard, J. Douglas Wright
We consider the mass-in-mass (MiM) lattice when the internal resonators are very small. When there are no internal resonators the lattice reduces to a standard Fermi-Pasta-Ulam-Tsi…
