Symmetry breakings in dual-core systems with double-spot localization of nonlinearity
Krzysztof B. Zegadlo, Nguyen Viet Hung, Aleksandr Ramaniuk +2
We introduce a dual-core system with double symmetry, one between the cores, and one along each core, imposed by the spatial modulation of local nonlinearity in the form of two tig…
Single and double linear and nonlinear flatband chains: spectra and modes
Krzysztof B. Zegadlo, Nir Dror, Nguyen Viet Hung +2
We report results of systematic analysis of various modes in the flatband lattice, based on the diamond-chain model with the on-site cubic nonlinearity, and its double version with…
Stabilization of solitons under competing nonlinearities by external potentials
Krzysztof B. Zegadlo, Tomasz Wasak, Boris A. Malomed +2
We report results of the analysis for families of one-dimensional (1D) trapped solitons, created by competing self-focusing (SF) quintic and self-defocusing (SDF) cubic nonlinear t…
