Two-photon absorption and its characteristics in field-emission energy distributions

A conceptual model is developed for the processes of photon emission and absorption. While the emission of light is well known in terms of quantum changes in energy levels of an electron, the fundamental physical processes are incompletely understood. How exactly does the photon emerge from the electron? How is light absorbed by matter? These foundational conceptual questions are the focus of this paper. We show that it is possible to develop new insights into this problem, based on the cordus model, which is a non-local hidden-variable solution. We start by predicting the structures of the photon and electron, both the internal geometric substructures, and their discrete fields. The model predicts that there are different mechanisms for the fields of the photon and electron, and uses this to explain the characteristics of the evanescent and electric fields. We then show how the bonding constraints arise on the electron, and how these require the electron to emit its excess energy. The process whereby a photon is created and separated out of the electron is identified. Photon emission and absorption thus result from an interaction between the discrete field elements and the internal structures. Emission is thus an escapement mechanism whereby matter particules that are overprescribed in position can get rid of that energy.

This is the third companion paper to the Relative Field Localization (RFL) framework (RFL v8.0). It presents a physical account of Compton scattering in which the photon is absorbed by the extended charge distribution, the electron gains the photon energy, the charge localizes into a Q-ball at the peak of j^0, and a new photon is re-emitted from the peak. This mechanism provides a direct physical explanation for:• Why the scattered photon loses energy• Why it emerges from a definite spatial location• How energy loss is tied to the localization process The account proceeds in four stages:1. Absorption: The incoming photon is fully absorbed by the extended charge.2. Excitation: The electron gains the photon energy (ΔE_e = E_γ).3. Localization: The gained energy drives the charge to localize into a Q-ball at the peak x_α.4. Re-emission: A new photon is emitted from the peak, carrying the remaining energy E_γ'. Energy conservation is exact:E_γ = E_γ' + E_Q-ball + E_kin In the simplest case, the energy loss is set by the characteristic Q-ball scale:ΔE_γ ~ ħ ω_C The treatment follows the RFL localization law τ_loc = S_RL · L³ · m² and is consistent with the standard Compton result in the appropriate limit. The finite time delay between absorption and re-emission is of order τ_loc. This paper is the third in a series of three companion papers. The other two are:• RFL Applications I: Thermal Effects in Quantum Computing• RFL Applications II: Double-Slit Interference

The absorption and the emission of photons by an atom involves quantum jumps between states. We investigate the quantum jump statistics for the system of a two-level atom and a single-mode cavity field. We use the Jaynes-Cummings model for this problem, perform Monte Carlo numerical simulations, and give a detailed exact analysis on these simulations. These studies reveal that the waiting-time distribution (WTD) for photon absorptions (emissions) has a unique novel statistic, and that the photon absorption (emission) rate is not uniform, but counter-intuitively depends on the position in the Rabi cycle. The effects of the nonclassical nature of the field on the WTD is discussed.
