▎ 摘　　要

We derive the differential probability of the photoelectric effect realized at the very low temperature of double graphene in the strong magnetic field (The magnetic photoelectric effect). The relation of this effect to the elementary particle physics, nuclear physics and Einstein gravity is mentioned. Our approach is the nanalogue of the Landau theory of the diamagnetism. Understanding of the photoelectric effect on graphene enables the understanding of the photosynthesis in the chlorophyll in magnetic field.
