Abstract
Luminescence in certain doped alkali halide crystals does not decay exponentially. The explanation (for the examples we study) lies in the formation of non-linear excitations called breathers which appear to live on two-dimensional KAM tori. Quantization of the breathers is accomplished using a stroboscopic method.
