Breather stripes and radial breathers of the two-dimensional sine-Gordon equation
(Elsevier, 2021-03)We revisit the problem of transverse instability of a 2D breather stripe of the sine-Gordon (sG) equation. A numerically ...

Escape dynamics in the discrete repulsive φ4 model
(2013)We study deterministic escape dynamics of the discrete Klein-Gordon model with a repulsive quartic on-site potential. Using ...

Existence, stability and spatio-temporal dynamics of time-quasiperiodic solutions on a finite background in discrete nonlinear Schrödinger models
(Elsevier, 2024-07)In the present work we explore the potential of models of the discrete nonlinear Schrödinger (DNLS) type to support spatially ...

Frequency–momentum representation of moving breathers in a two dimensional hexagonal lattice
(ScienceDirect, 2022-12)We study nonlinear excitations propagating in a hexagonal layer which is a model for the cation layer of silicates. We ...

Nonlinear waves in a model for silicate layers
(American Institute of Physics, 2018-08-24)Some layered silicates are composed of positive ions, surrounded by layers of ions with opposite sign. Mica muscovite is ...

Pterobreathers in a model for a layered crystal with realistic potentials: Exact moving breathers in a moving frame
(American Physical Society, 2019-08-12)In this article we perform a thorough analysis of breathers in a one-dimensional model for a layered silicate for which ...

Revisiting multi-breathers in the discrete Klein–Gordon equation: a spatial dynamics approach
(IOP Publishing, 2022-11)We consider the existence and spectral stability of multi-breather structures in the discrete Klein–Gordon equation, both ...
