摘要: We present an efficient method to calculate probabilities of large deviations from the typical behavior (rare events) in reaction-diffusion systems. This is based on a semiclassical treatment underlying ``quantum'' Hamiltonian, encoding system's evolution. To this end, we formulate corresponding canonical dynamical system and investigate its phase portrait. presented for number pedagogical examples.
