Dark lattice solitons in one-dimensional waveguide arrays with defocusing saturable nonlinearity and alternating couplings
(2012)
In the present work, we examine “binary” waveguide arrays, where the coupling between adjacent sites alternates between two distinct values C1 and C2 and a saturable nonlinearity is present on each site. Motivated by ...

Symmetry-breaking Effects for Polariton Condensates in Double-Well Potentials
(Springer Verlag, 2012)
We study the existence, stability, and dynamics of symmetric and anti-symmetric states of quasi-one-dimensional polariton condensates in double-well potentials, in the presence of nonresonant pumping and nonlinear damping. ...

Beating dark-dark solitons in Bose-Einstein condensates
(2012)
Motivated by recent experimental results, we study beating dark-dark solitons as a prototypical coherent structure that emerges in two-component Bose-Einstein condensates. We showcase their connection to dark- bright ...

Breathers and surface modes in oscillator chains with Hertz ian interactions
(NOLTA, 2012)
We study localized waves in chains of oscillators coupled by Hertzian interactions and trapped in local potentials. This problem is originally motivated by Newton's cradle, a mechanical system consisting of a chain of ...
