A Lorentz-covariant localization for light waves is presented. The unitary representation for the electromagnetic four-potential is constructed for a monochromatic light wave. A model for covariant superposition is constructed for light waves with different frequencies. It is therefore possible to construct a wave function for light waves carrying a covariant probability interpretation. It is shown that the time-energy uncertainty relation (\ensuremath{\Delta}t)(\ensuremath{\Delta}\ensuremath{\omega})\ensuremath{\simeq}1 for light waves is a Lorentz-invariant relation. The connection between photons and localized light waves is examined critically.A Lorentz-covariant localization for light waves is presented.

Second-Order Duality of Light and its Nonclassical Complementarity

Rikizo Ikuta

A single photon exhibits wave-particle duality in the Young's double-slit interferometer. The duality character-ized by an interference visibility $V$ as the wave-like property and a which-path information $D$ as the particle-like property has tradeoff relation $D^{2}+V^{2}\leq 1$ known as complementarity [1]–[3]. There are a lot of studies about the complementary nature of photons from various viewpoints such as delayed-choice experiments, theoretical works related to the uncertainty principle, and so on. More recently, studies have expanded the concept of the wave-particle duality to higher-order interferometric scenarios, in which the input light includes two or more pho-tons [4], [5]. Despite having a long history, all previous studies have been related to phase correlation of optical states, which reason would be why the main focus in the first place is the investigation of the mysterious quantum nature of a photon, including the superposition principle.A single photon exhibits wave-particle duality in the Young's double-slit interferometer.

Highlighting relations between Wave-particle duality, Uncertainty principle, Phase space and Microstates

Ravo Tokiniaina Ranaivoson, Voriraza Séraphin Hejesoa, Raoelina Andriambololona +5 more

Wave-particle duality is often considered as the modern answer to the problem of the nature of light after more than 2000 years of questioning. It is also the answer given by quantum physics concerning the nature of matter particles and any other radiations. The main objective of this work is to analyze the relations that are existing between this concept of wave-particle duality, the uncertainty principle and the concepts of phase space and microstates considered in statistical mechanics. It is mainly highlighted that while the concepts of phase space and microstates were already introduced in classical physics before the discovery of the wave-particle duality, a correct understanding of them cannot be achieved without the use of the concept of quantum phase space and phase space representation of quantum mechanics which are directly related to the uncertainty principle. The possibility of using these concepts of quantum phase space and phase space representations of quantum mechanics to help in a deeper description of the wave-particle duality and in the study of some current issues related to foundational problems of quantum mechanics like quantum decoherence and the measurement problem is also discussed.Wave-particle duality is often considered as the modern answer to the problem of the nature of light after more than 2000 years of questioning.
