Solitary wave billiards
(American Physical Society, 2023-03)
In the present work we explore the concept of solitary wave billiards. That is, instead of a point particle, we examine a solitary wave in an enclosed region and examine its collision with the boundaries and the resulting ...

Discrete breathers in Klein–Gordon lattices. A deflation-based approach
(American Institute of Physics, 2023-11-21)
Deflation is an efficient numerical technique for identifying new branches of steady state solutions to nonlinear partial differential equations. Here, we demonstrate how to extend deflation to discover new periodic orbits ...

Standing and traveling waves in a model of periodically modulated one-dimensional waveguide arrays
(American Physical Society, 2023-08)
In the present work we study coherent structures in a one-dimensional discrete nonlinear Schrödinger lattice in which the coupling between waveguides is periodically modulated. Numerical experiments with single-site initial ...
