[HTML][HTML] Reviving modulational instability with third-order dispersion

K Tamilselvan, A Govindarajan, T Kanna… - Physics Letters A, 2022 - Elsevier
It is well-known that third-order dispersion (TOD) plays no role in the onset of modulation
instability in the nonlinear Schrödinger (NLS) family of systems. Here we demonstrate that …

Siguiendo la idea del Juego de los Abalorios (de Hermann Hesse), en este trabajo
investigamos qué relación existe entre el último Teorema de Fermat (UTF) y los solitones …

Dispersion relations and band gaps in wave number or frequency in the linear and nonlinear regimes for a coupled system with no paraxial approximation

M Kumar, K Porsezian, K Nithyanandan - AIP Conference Proceedings, 2018 - pubs.aip.org
We study the linear and nonlinear pulse propagation models whose dispersion relations
presents bands of forbidden frequencies or forbidden wave numbers. These bands are due …
