Multichannel asymmetric transmission through a dimer defect with saturable inter-site nonlinearity
Muhammad Abdul Wasay, Magnus Johansson
We consider the asymmetric transmission properties of a Discrete Nonlinear Schr{ö}dinger type dimer with a saturable nonlinear intersite coupling between the dimer sites, in additi…
Nonlinear gap modes and compactons in a lattice model for spin-orbit coupled exciton-polaritons in zigzag chains
Magnus Johansson, Petra P. Beličev, Goran Gligorić +2
We consider a system of generalized coupled Discrete Nonlinear Schrödinger (DNLS) equations, derived as a tight-binding model from the Gross-Pitaevskii-type equations describing a…
Compactification tuning for nonlinear localized modes in sawtooth lattices
Magnus Johansson, Uta Naether, Rodrigo A. Vicencio
We discuss the properties of nonlinear localized modes in sawtooth lattices, in the framework of a discrete nonlinear Schrödinger model with general on-site nonlinearity. Analytic…
Breather mobility and the PN potential: Brief review and recent progress
Magnus Johansson, Peter Jason
The question whether a nonlinear localized mode (discrete soliton/breather) can be mobile in a lattice has a standard interpretation in terms of the Peierls-Nabarro (PN) potential…
Strongly localized moving discrete dissipative breather-solitons in Kerr nonlinear media supported by intrinsic gain
Magnus Johansson, Jaroslaw E. Prilepsky, Stanislav A. Derevyanko
We investigate the mobility of nonlinear localized modes in a generalized discrete Ginzburg-Landau type model, describing a one-dimensional waveguide array in an active Kerr medium…
Discrete flat-band solitons in the Kagome lattice
Rodrigo A. Vicencio, Magnus Johansson
We consider a model for a two-dimensional Kagome-lattice with defocusing nonlinearity, and show that families of localized discrete solitons may bifurcate from localized linear mod…
