Different viewpoints of electric dipole-electric dipole interaction in the calculation of the energy transfer rate of rare earth ions in insulators
The physical mechanism of the electric dipole-electric dipole (ED-ED) interaction may be looked at from several viewpoints in the calculation of the ED-ED energy transfer rate of rare earth ions in insulators. In this article, we demonstrate the equivalence of the results calculated from taking the ED-ED interaction as an energy transfer operation, or as a correction operator to the zero-order wavefunction of the donor-acceptor system.
