We study the energy spectrum of the strong-coupled superlattice. The barriers affect the energy spectral statistics in a small scale. The nearest-neighbor energy-level distribution P(s) and the spectral rigidity Δ 3 (L) demonstrated the GOE (Gaussian Orthogonal Ensemble) distribution. In the whole scale, with the electric field increasing, the spectral rigidity Δ 3 (L) changes from...
A new method to predict the average lifetime of a chaotic transient versus a system parameter is studied for the case that a chaotic attractor is converted into a chaotic transient upon a boundary crisis. This method is compared with numerical experiments using four maps with different critical exponents.
