Nonlinear multi-core waveguiding structures with balanced gain and loss
Alejandro J. Martínez, Mario I. Molina, Sergei K. Turitsyn +1
We study existence, stability, and dynamics of linear and nonlinear stationary modes propagating in radially symmetric multi-core waveguides with balanced gain and loss. We demonst…

Expansion of a wave-packet in lattices with disorder and nonlinearity
Uta Naether, Santiago Rojas-Rojas, Alejandro J. Martinez +6
We show, theoretically and experimentally, the counterintuitive result that an increase of disorder can result in an enhanced spreading of an initially localized excitation. Moreov…
