Electrons exist in a material lattice in a naturally random state. Photons,being neutral energy carriers without charge, can, under certain conditionsof threshold energy, directionality, and density, force the alignmentof electron degrees of freedom and directionality.Remark: It is more precise to say that photons reorganize the statespace of electrons rather than “push” electrons. newbalancems@naver.com
