    • 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 ...
    • Fano resonances in magnetic metamaterials 
      Naether, Uta; Molina Gálvez, Mario (2011)
      We study the scattering of magnetoinductive plane waves by internal (external) capacitive (inductive) defects coupled to a one-dimensional split-ring resonator array. We examine a number of simple defect configurations ...
    • Fano resonances in waveguide arrays with saturable nonlinearity 
      Naether, Uta; Rivas, Daniel E.; Larenas, Manuel A.; Molina Gálvez, Mario; Vicencio Poblete, Rodrigo (Optical Society of America (OSA), 2009)
      We study a waveguide array with an embedded nonlinear saturable impurity. We solve the impurity problem in closed form and find the nonlinear localized modes. Next, we consider the scattering of a small-amplitude plane ...
    • Nonlinear localized modes in dipolar Bose-Einstein condensates in two-dimensional optical lattices 
      Rojas Rojas, Santiago; Naether, Uta; Delgado, Aldo; Vicencio Poblete, Rodrigo (Elsevier B.V., 2016)
      © 2016 Elsevier B.V. We analyze the existence and properties of discrete localized excitations in a Bose-Einstein condensate loaded into a periodic two-dimensional optical lattice, when a dipolar interaction between atoms ...
    • Nonlinear localized modes in dipolar Bose–Einstein condensates in two-dimensional optical lattices 
      Rojas Rojas, Santiago; Naether, Uta; Delgado, Aldo; Vicencio Poblete, Rodrigo (Elsevier Science BV., 2016)
      We analyze the existence and properties of discrete localized excitations in a Bose-Einstein condensate loaded into a periodic two-dimensional optical lattice, when a dipolar interaction between atoms is present. The ...
