Universal Selftrapping in Nonlinear Tight-binding Lattices
C. A. Bustamante, M. I. Molina
We show that nonlinear tight-binding lattices of different geometries and dimensionalities, display an universal selftrapping behavior. First, we consider the single nonlinear impu…

Selftrapping and Quantum Fluctuations in the Discrete Nonlinear Schrodinger Equation
C. A. Bustamante, M. I. Molina
We study the robustness of the selftrapping phenomenon exhibited by the Discrete Nonlinear Schrodinger (DNLS) equation against the effects of nonadiabaticity and quantum fluctuatio…
