Nonlinear excitations in magnetic lattices with long-range interactions

M Molerón, C Chong, AJ Martínez… - New Journal of …, 2019 - iopscience.iop.org
We study—experimentally, theoretically, and numerically—nonlinear excitations in lattices of
magnets with long-range interactions. We examine breather solutions, which are spatially …

Temperature dependence of heat conduction in the Fermi-Pasta-Ulam- lattice with next-nearest-neighbor coupling

D Xiong, Y Zhang, H Zhao - Physical Review E, 2014 - APS
We show numerically that introducing the next-nearest-neighbor interactions (of appropriate
strength) into the one-dimensional (1D) Fermi-Pasta-Ulam-β (FPU-β) lattice can result in an …

Dark solitons, modulation instability and breathers in a chain of weakly nonlinear oscillators with cyclic symmetry

F Fontanela, A Grolet, L Salles, A Chabchoub… - Journal of sound and …, 2018 - Elsevier
In the aerospace industry the trend for light-weight structures and the resulting complex

Backward-and forward-wave soliton coexistence due to second-neighbor coupling in a left-handed transmission line

D Mahmoud, S Abdoulkary, LQ English… - Nonlinear …, 2022 - Springer
We study analytically and numerically the impact of the second-neighbor interactions on the
propagation of an initial wave-packet through a coupled nonlinear left-handed transmission …

Thermal rectification in mass-graded next-nearest-neighbor Fermi-Pasta-Ulam lattices

M Romero-Bastida, JO Miranda-Pena, JM López - Physical Review E, 2017 - APS

one-dimensional mass-graded anharmonic oscillator Fermi-Pasta-Ulam lattice both with …

Mobility of discrete multibreathers in the exciton dynamics of the Davydov model with saturable nonlinearities

JD Tchinang Tchameu, AB Togueu Motcheyo… - Physical Review E, 2014 - APS
We show that the state of amide-I excitations in proteins is modeled by the discrete nonlinear
Schrödinger equation with saturable nonlinearities. This is done by extending the Davydov …

Separable graph Hamiltonian network: A graph deep learning model for lattice systems
