“…With the development of a robust theory rigorously based on quantum electrodynamics [3], it has become possible to encompass a complete photon history as an embodiment of the causal linkage between source decay and detector excitation events [4]. In the QED representation, the propagation of light from an emissive source to an absorptive detector is the long-range limit of a general mechanism that, when it operates over subwavelength distances, is usually designated resonance energy transfer [5].…”

The premise that multipolar decay should produce photons uniquely imprinted with a measurably corresponding angular momentum is shown in general to be untrue. To assume a one-to-one correlation between the transition multipoles involved in source decay and detector excitation is to impose a generally unsupportable one-to-one correlation between the multipolar form of emission transition and a multipolar character for the detected field. It is specifically proven impossible to determine without ambiguity, by use of any conventional detector, and for any photon emitted through the nondipolar decay of an atomic excited state, a unique multipolar character for the transition associated with its generation. Consistent with the angular quantum uncertainty principle, removal of a detector from the immediate vicinity of the source produces a decreasing angular uncertainty in photon propagation direction, reflected in an increasing range of integer values for the measured angular momentum. In such a context it follows that when the decay of an electronic excited state occurs by an electric quadrupolar transition, for example, any assumption that the radiation so produced is conveyed in the form of "quadrupole photons" is experimentally unverifiable. The results of the general proof based on irreducible tensor analysis invite experimental verification, and they signify certain limitations on quantum optical data transmission.

“…[46][47][48] As with the optically induced pair forces, the throughput radiation once again emerges in a final state that is unchanged from its initial state, while in this case the material system experiences a transfer of energy from A to B. Thus, for the initial and final states of the system as a whole we have ͉I͘ = ͉A ␣ ,B 0 ;n͑p,l͒͘, ͉F͘ = ͉A 0 ,B ␤ ;n͑p,l͒͘.…”

Electronically excited molecules interact with their neighbors differently from their ground-state counterparts. Any migration of the excitation between molecules can modify intermolecular forces, reflecting changes to a local potential energy landscape. It emerges that throughput off-resonant radiation can also produce significant additional effects. The context for the present analysis of the mechanisms is a range of chemical and physical processes that fundamentally depend on intermolecular interactions resulting from second and fourth-order electric-dipole couplings. The most familiar are static dipole-dipole interactions, resonance energy transfer ͑both second-order interactions͒, and dispersion forces ͑fourth order͒. For neighboring molecules subjected to off-resonant light, additional forms of intermolecular interaction arise in the fourth order, including radiation-induced energy transfer and optical binding. Here, in a quantum electrodynamical formulation, these phenomena are cast in a unified description that establishes their inter-relationship and connectivity at a fundamental level. Theory is then developed for systems in which the interplay of these forms of interaction can be readily identified and analyzed in terms of dynamical behavior. The results are potentially significant in Förster measurements of conformational change and in the operation of microelectromechanical and nanoelectromechanical devices.

“…For present purposes, equation (1) can be regarded as being applied to a system comprising just two material components, ξ signifying the source/donor or the detector/acceptor. By inspection of this expression it is immediately apparent that, in contrast to most classical descriptions, energy transfer is not mediated by instantaneous coupling interactions-note the absence of any terms connecting different chromophores-but causally, through an electromagnetic field with a finite speed of propagation [21]. The term of most interest in equation (1) is the interaction term, since the light-matter interactions act as a perturbation to the total energy of the particles and the fields in isolation.…”

Identifying the development in phase and amplitude of dipole and multipole radiation

The spatial variation in phase and the propagating wave-front of plane wave electromagnetic radiation are widely familiar text-book territory. In contrast, the developing amplitude and phase of radiation emitted by a dipole or multipole source generally receive less attention, despite the prevalence of these systems. There is additional complexity in such cases where, in consequence of retardation, the character and features significantly and progressively change as radiation propagates onwards, from the near-field and out towards the wavezone. Readily developed analytical representations of the electric field, cast as a function of distance from the source, provide illuminating insights into the most prominent and distinctive properties of radiant electromagnetic emission. Graphical implementations and animations of the results prove particularly instructive in revealing the spatial form and temporal evolution of the emergent electromagnetic fields.
