We study the pump-probe response of three insulating cuprates and develop a model for its recombination kinetics. The dependence on time. fluence. and both pump and probe photon energies implies many-body recombination on femtosecond timescales. https://www.getpureroutine.com/hot-sale-ethical-nutrients-mega-magnesium-powder-citrus-450g-for-sale-save-big/
