Controlled transport based on multiorbital Aharonov-Bohm photonic caging

G Cáceres-Aravena, D Guzmán-Silva, I Salinas… - Physical Review Letters, 2022 - APS
The induction of synthetic magnetic fields on lattice structures allows an effective control of
their localization and transport properties. In this Letter, we generate effective π magnetic …

Experimental observation of edge states in SSH-Stub photonic lattices

G Cáceres-Aravena, B Real, D Guzmán-Silva… - Physical Review …, 2022 - APS
We reveal unconventional edge states in a one-dimensional Stub lattice of coupled
waveguides with staggered hoppings. The edge states appear for the same values of …

Diffraction-free image transmission in kagome photonic lattices

RA Vicencio, C Mejía-Cortés - Journal of Optics, 2013 - iopscience.iop.org
We study the propagation of non-diffracting images in kagome photonic lattices. In a weak-
coupling regime (discrete approach), the linear spectrum is composed by only three bands …

Superdiffusive transport and energy localization in disordered granular crystals

AJ Martínez, PG Kevrekidis, MA Porter - Physical Review E, 2016 - APS
We study the spreading of initially localized excitations in one-dimensional disordered
granular crystals. We thereby investigate localization phenomena in strongly nonlinear …

Stationary discrete solitons in a driven dissipative Bose-Hubbard chain

U Naether, F Quijandría, JJ García-Ripoll, D Zueco - Physical Review A, 2015 - APS
We demonstrate that stationary localized solutions (discrete solitons) exist in one-
dimensional Bose-Hubbard lattices with gain and loss in a semiclassical regime. Stationary …

Enhanced distribution of a wave-packet in lattices with disorder and nonlinearity

U Naether, S Rojas-Rojas, AJ Martínez, S Stützer… - Optics …, 2013 - opg.optica.org
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 …

Strain induced localization to delocalization transition on a Lieb photonic ribbon lattice

D Román-Cortés, G Fadic, C Cid-Lara… - Scientific Reports, 2021 - nature.com
Ribbon lattices are kind of transition systems in between one and two dimensions, and their
study is crucial to understand the origin of different emerging properties. In this work, we …

Localized modes in linear and nonlinear octagonal-diamond lattices with two flat bands

MG Stojanović, MS Krasić, A Maluckov, M Johansson… - Physical Review A, 2020 - APS
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 …

Quantum chaos in an ultrastrongly coupled bosonic junction

U Naether, JJ García-Ripoll, JJ Mazo, D Zueco - Physical Review Letters, 2014 - APS
The semiclassical and quantum dynamics of two ultrastrongly coupled nonlinear resonators
cannot be explained using the discrete nonlinear Schrödinger equation or the Bose …

Chaos on a saturable optical dimer

RA Vicencio, MG Clerc - Chaos, Solitons & Fractals, 2021 - Elsevier
A pair of periodically coupled and forced simple oscillators can exhibit aperiodic behaviors.
Here we study the effect of periodic spatial modulations in an optical dimer composed of …
