Quantum electrodynamics in photonic crystals and controllability of ionization energy of atoms

The periodic changes in the physical and chemical properties of elements are caused by change ionization energies, which constant for each element that manifested Periodic Table. However, as has been recently shown modification electromagnetic field photonic crystals gives rise to electron mass. We show effect can significantly energy atoms placed voids consisting metamaterials with a highly tunable refractive index voids. controllability these materials energies over wide range.
