Stationary discrete solitons in circuit QED
Uta Naether, Fernando Quijandría, Juan José García-Ripoll +1
We demonstrate that stationary localized solutions (discrete solitons) exist in a one dimensional Bose-Hubbard lattices with gain and loss in the semiclassical regime. Stationary s…
Random dimer model in pseudo two-dimensional lattices
Uta Naether, Cristian Mejía-Cortés, Rodrigo A. Vicencio
In this work, we study long-time wave transport in correlated and uncorrelated disordered 2D arrays. When a separation of dimensions is applied to the model, we find that the predi…
Analytical model for waveguide light propagation and applications
Santiago Rojas Rojas, Luis Morales-Inostroza, Uta Naether +6
We study the polarization properties of elliptical femtosecond-laser-written waveguides arrays. A new analytical model is presented to explain the asymmetry of the spatial transver…
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…
