A detailed numerical analysis for a small range of the nonlinearity parameter exhibits the existence of a sharp order window for the n = 3 discrete self-trapping equation. The analysis performed by using maximum Lyapunov characteristic exponent, power spectra, Poincaré maps and correlation exponents gives a clear-cut evidence of a biperiodic dynamics on bidimensional tori.

Abstract
A detailed numerical analysis for a small range of the nonlinearity parameter exhibits the existence of a sharp order window for the n = 3 discrete self-trapping equation. The analysis performed by using maximum Lyapunov characteristic exponent, power spectra, Poincaré maps and correlation exponents gives a clear-cut evidence of a biperiodic dynamics on bidimensional tori.File in questo prodotto:
