Control of wavepacket spreading in nonlinear finite disordered lattices
Rodrigo A. Vicencio And Sergej Flach
In the absence of nonlinearity all normal modes (NMs) of a chain with disorder are spatially localized (Anderson localization). We study the action of nonlinearity, whose strength…
Saturable discrete vector solitons in one-dimensional photonic lattices
Rodrigo A. Vicencio, Eugene Smirnov, Christian E. Rüter +2
Localized vectorial modes, with equal frequencies and mutually orthogonal polarizations, are investigated both analytically and experimentally in a one-dimensional photonic lattice…
Fano blockade by a Bose-Einstein condensate in an optical lattice
Rodrigo A. Vicencio, Joachim Brand, Sergej Flach
We study the transport of atoms across a localized Bose-Einstein condensate in a one-dimensional optical lattice. For atoms scattering off the condensate we predict total reflectio…
Two-color discrete localized modes and resonant scattering in arrays of nonlinear quadratic optical waveguides
M. I. Molina, R. A. Vicencio, Y. S. Kivshar
We analyze the properties and stability of two-color discrete localized modes in arrays of channel waveguides where tunable quadratic nonlinearity is introduced as a nonlinear defe…
Discrete solitons and nonlinear surface modes in semi-infinite waveguide arrays
M. I. Molina, R. A. Vicencio, Y. S. Kivshar
We discuss the formation of self-trapped localized states near the edge of a semi-infinite array of nonlinear waveguides. We study a crossover from nonlinear surface states to disc…
Discrete soliton mobility in two-dimensional waveguide arrays with saturable nonlinearity
Rodrigo A. Vicencio, Magnus Johansson
We address the issue of mobility of localized modes in two-dimensional nonlinear Schrödinger lattices with saturable nonlinearity. This describes e.g. discrete spatial solitons in…
