Role of breathers in anomalous decay.
We have previously presented evidence for the formation of breathers in doped alkali halides subjected to a flash of UV light. Properties of these breathers, their phase space structure, robustness, decay, and propensity for formation, are studied here. Under a wide range of parameters and interionic potentials they form two-dimensional Kolmogorov-Arnold-Moser tori (less than generic) in phase space. Strobed views of these tori, useful in quantization, are shown. All features support the thesis of breather formation as the explanation for the luminescence decay anomaly that first motivated our breather proposal.
