Edge solitons in nonlinear-photonic topological insulators

D Leykam, YD Chong - Physical review letters, 2016 - APS
We show theoretically that a photonic topological insulator can support edge solitons that
are strongly self-localized and propagate unidirectionally along the lattice edge. The …

[HTML][HTML] On the proximity between the wave dynamics of the integrable focusing nonlinear Schrödinger equation and its non-integrable generalizations

D Hennig, NI Karachalios, D Mantzavinos… - Journal of Differential …, 2024 - Elsevier
The question of whether features and behaviors that are characteristic to completely
integrable systems persist in the transition to non-integrable settings is a central one in the …
