Soliton molecules in Fermi-Pasta-Ulam-Tsingou lattice: Gardner equation approach
M. Kirane, S. Stalin, R. Arun +1
We revisit the Fermi-Pasta-Ulam-Tsingou lattice (FPUT) with quadratic and cubic nonlinear interactions in the continuous limit by deducing the Gardner equation. Through the Hirota…
Coupled Nonlinear Schrödinger System: Role of Four-Wave Mixing Effect on Nondegenerate Vector Solitons
R. Ramakrishnan, M. Kirane, S. Stalin +1
In this paper, we investigate the role of four-wave mixing effect on the structure of nondegenerate vector solitons and their collision dynamics. For this purpose, we consider the…
Modulational instability in -symmetric Bragg grating structures with saturable nonlinearity
K. Tamilselvan, A. Govindarajan, I. Inbavalli +2
We investigate the nontrivial characteristics of modulational instability (MI) in a system of Bragg gratings with saturable nonlinearity. We also introduce an equal amount of gain…
Bright, dark and breather soliton solutions of the generalized long-wave short-wave resonance interaction system
M. Kirane, S. Stalin, M. Lakshmanan
In this paper, a generalized long-wave short-wave resonance interaction system, which describes the nonlinear interaction between a short-wave and a long-wave in fluid dynamics, pl…
Nondegenerate bright solitons in coupled nonlinear Schrödinger systems: Recent developments on optical vector solitons
S. Stalin, R. Ramakrishnan, M. Lakshmanan
Nonlinear dynamics of an optical pulse or a beam continue to be one of the active areas of research in the field of optical solitons. Especially, in multi-mode fibers or fiber arra…
Modulational instability in non-Kerr photonic Lieb lattice with metamaterials
A. K. Shafeeque Ali, Andrei I. Maimistov, K. Porsezian +2
We present an analysis of modulational instability of diffractionless waves in a face-centered square lattice of waveguides featuring non-Kerr nonlinearity, which are constituted b…
