Nonlinear Anti-(Parity-Time) symmetric dimer
A. S. Rodrigues, R. M. Ross, V. V. Konotop +2
In the present work we propose a nonlinear anti--symmetric dimer, that at the linear level has been experimentally created in the realm of electric circuit resonators…

Solitary waves with intensity-dependent dispersion: variational characterization
D. E. Pelinovsky, R. M. Ross, P. G. Kevrekidis
A continuous family of singular solitary waves exists in a prototypical system with intensity-dependent dispersion. The family has a cusped soliton as the limiting lowest energy st…

Localization in optical systems with an intensity-dependent dispersion
R. M. Ross, P. G. Kevrekidis, D. E. Pelinovsky
We address the nonlinear Schrodinger equation with intensity-dependent dispersion which was recently proposed in the context of nonlinear optical systems. Contrary to the previous…
