    • Localized modes in linear and nonlinear octagonal-diamond lattices with two flat bands 
      Stojanovic, M. G.; Krasic, M. Stojanovic; Maluckov, A.; Johansson, M.; Salinas, I. A.; Vicencio, R. A.; Stepic, M. (Amer Physical Soc, 2020)
      We consider a two-dimensional octagonal-diamond network with a fine-tuned diagonal coupling inside the diamond-shaped unit cell. Its linear spectrum exhibits coexistence of two dispersive bands (DBs) and two flat bands ...
    • Spatial rogue waves in photorefractive SBN crystals 
      Hermann Avigliano, C.; Salinas, I. A.; Rivas, D. A.; Real, B.; Mančić, A.; Mejía-Cortés, C.; Maluckov, A.; Vicencio, R. A. (OSA - The Optical Society, 2019)
      We report on the excitation of large-amplitude waves, with a probability of around 1% of total peaks, on a photorefractive SBN crystal by using a simple experimental setup at room temperature. We excite the system using a ...
