By controlling the number of sites with a given illumination, different percolation thresholds for propagation are observed, which depend on the relative wave transmittances of the two-state medium considered.4 p.application/pdfeng(c) The American Physical Society, 1998Teoria quànticaTeoria de camps (Física)Relativitat especial (Física)Física estadísticaTermodinàmicaQuantum theoryField theory (Physics)Special relativity (Physics)Statistical physicsThermodynamicsinfo:eu-repo/semantics/article144779info:eu-repo/semantics/openAccess
