Dark soliton scattering in symmetric and asymmetric double potential barriers
Tsitoura, F.; Anastassi, Z.A.; Marzuola, J.L.; Kevrekidis, P.G.; Frantzeskakis, D.J. ( Elsevier B.V. , 2017 , Article)Motivated by the recent theoretical study of (bright) soliton diode effects in systems with multiple scatterers, as well as by experimental investigations of soliton-impurity interactions, we consider some prototypical ... -
Spatiotemporal algebraically localized waveforms for a nonlinear Schrödinger model with gain and loss
Anastassi, Z.A.; Fotopoulos, G.; Frantzeskakis, D.J.; Horikis, T.P.; Karachalios, N.I.; Kevrekidis, P.G.; Stratis, I.G.; Vetas, K.... more authors ... less authors ( Elsevier B.V. , 2017 , Article)We consider the asymptotic behavior of the solutions of a nonlinear Schrödinger (NLS) model incorporating linear and nonlinear gain/loss. First, we describe analytically the dynamical regimes (depending on the gain/loss ...
