    • Enhanced distribution of a wave-packet in lattices with disorder and nonlinearity 
      Naether, Uta; Rojas Rojas, Santiago; Martínez, Alejandro J.; Stützer, Simon; Tünnermann, Andreas; Nolte, Stefan; Molina Gálvez, Mario; Vicencio Poblete, Rodrigo; Szameit, Alexander (Optical Society of America, 2013-01)
      We show, numerically and experimentally, that the presence of weak disorder results in an enhanced energy distribution of an initially localized wave-packet, in one- and two-dimensional finite lattices. The addition of ...
    • Experimental observation of superdiffusive transport in random dimer lattices 
      Naether, U.; Stützer, S.; Vicencio Poblete, Rodrigo; Molina Gálvez, Mario; Tünnermann, A.; Nolte, S.; Kottos, T.; Christodoulides, D.N.; Szameit, A. (IOP Publishing Ltd and Deutsche Physikalische Gesellschaft, 2013)
      We experimentally observe anomalous wavepacket evolution in a realization of a one-dimensional finite binary Anderson model in the presence of short-range correlations. To this end, we employ weakly-coupled optical waveguides ...
    • Vortex solitons of the discrete Ginzburg-Landau equation 
      Mejía Cortés, Cristian; Soto Crespo, J. M.; Vicencio Poblete, Rodrigo; Molina Gálvez, Mario (AMER PHYSICAL SOC, 2011-04-29)
      We have found several families of vortex soliton solutions in two-dimensional discrete dissipative systems governed by the cubic-quintic complex Ginzburg-Landau equation. There are symmetric and asymmetric solutions, and ...
