Discrete solitons dynamics in -symmetric oligomers with complex-valued couplings
O. B. Kirikchi, N. Karjanto
We consider an array of double oligomers in an optical waveguide device. A mathematical model for the system is the coupled discrete nonlinear Schrödinger (NLS) equations, where th…
Solitons in a chain of charge-parity-symmetric dimers
O. B. Kirikchi, B. A. Malomed, N. Karjanto +2
We consider an array of dual-core waveguides, which represent an optical realization of a chain of dimers, with an active (gain-loss) coupling between the cores, opposite signs of…
Snakes and ghosts in a parity-time-symmetric chain of dimers
H. Susanto, R. Kusdiantara, N. Li +4
We consider linearly coupled discrete nonlinear Schrödinger equations with gain and loss terms and with a cubic-quintic nonlinearity. The system models a parity-time ()-s…
Bright solitons in a PT-symmetric chain of dimers
Omar B. Kirikchi, Alhaji A Bachtiar, Hadi Susanto
We study the existence and stability of fundamental bright discrete solitons in a parity-time (PT)-symmetric coupler composed by a chain of dimers, that is modelled by linearly cou…
