Stationary states of a nonlinear Schrödinger lattice with a harmonic trap
V. Achilleos, G. Theocharis, P. G. Kevrekidis +3
We study a discrete nonlinear Schrödinger lattice with a parabolic trapping potential. The model, describing, e.g., an array of repulsive Bose-Einstein condensate droplets confined…

Breathers for the Discrete Nonlinear Schrödinger equation with nonlinear hopping
N. I. Karachalios, B. Sánchez-Rey, P. G. Kevrekidis +1
We discuss the existence of breathers and lower bounds on their power, in nonlinear Schrödinger lattices with nonlinear hopping. Our methods extend from a simple variational approa…
