The photon concept is one of the most debated issues in the history of physical science. Some thirty years ago, we published an article in Physics Today entitled "The Concept of the Photon," 1 in which we described the "photon" as a classical electromagnetic field plus the fluctuations associated with the vacuum. However, subsequent developments required us to envision the photon as an intrinsically quantum mechanical entity, whose basic physics is much deeper than can be explained by the… Expand

Quantum Mechanics of Photons
We present a short review of the concept of photon wave function and the photon wave equation which represents the Schrödinger equation for the photon. Photon wave function puts the photon on theExpand
The photon concept revisited: role of cooperative virtual processes in light harvesting
The usefulness of the photon concept has been debated since its original proposal by Einstein in 1905. The photon picture has evolved via the “fuzzy-ball” and stochastic to the entangled,Expand
Quantum mechanics without quanta: the nature of the wave–particle duality of light
In this paper, I argue that light is a continuous classical electromagnetic wave, while the observed so-called quantum nature of the interaction of light with matter is connected to the discreteExpand
The photon wave function
We review and sharpen the concept of a photon wave function based on the quantum theory of light. We argue that a point-like atom serves as the archetype for both the creation and detection ofExpand

There are two opposing points of view on the nature of light: the first one manifests the wave-particle duality as a fundamental property of the nature; the second one claims that photons do notExpand
Photon-based and classical descriptions in nanophotonics: a review
Abstract. The centrality of the photon concept in modern physics is strongly evident in wide spheres of photonics and nanophotonics. Despite the resilience and persistence of earlier classicalExpand

The wave-particle duality is a fundamental property of the nature. At the same time, it is one of the greatest mysteries of modern physics. This gave rise to a whole direction in quantum physics -Expand
Classical and quantum field aspects of light
This lecture (the first of three) discusses foundational problems on the nature of light revealed by attempts to define a probability concept for photons, quantum models for photons on demand (andExpand
Space-time description of transverse photons: near-field aspects
A mean position state based on the gauge invariant transverse vector potential is used to convert single-photon states in Hilbert space to photon wave packets in direct space. The resulting photonExpand
Different Perspective on Blue Sky Theory: Theory of Single-Photon Scattering on Bound and Free Electrons
We present a theory of light scattering consistent with modern physics. We proposed a spatial‐ temporal model of a photon based on classical model of an atomic oscillator. Using thisExpand
