WHATEVER view is held regarding the nature of light, it must. now be admitted that the process whereby an atom loses radiant energy, and another near or distant atom receives the same energy, is characterised by a remarkable abruptness and singleness. We are reminded of the process in which a molecule loses or gains a whole atom or a whole electron but never a fraction of one or the other. When the genius of Planck brought him to the first formulation of the quantum theory, a new kind of… 

The concept of the photon

The idea of the photon has stirred the imaginations of physicists ever since 1905 when Einstein originally proposed the use of light quanta to explain the photoelectric effect. This concept is

A photon in perspective

It is a familiar, fundamental truth of modern Physics that light is composed of photons, entities known as elementary particles despite possessing both particleand wave-like attributes. Readers of

The conservation of light's energy, mass, and momentum

An advance in the foundations of quantum mechanics was presented at the previous "Nature of Light" meeting which brings new insights to the conservation of light's energy, mass and momentum. Those

Boson Model of Quantized EM-Field and Nature of Photons

The fundamental result, obtained by Dirac, that the dynamical system, which consists of the ensemble of identical bosons is equivalent to the dynamical system, which consists of the ensemble of

A richly diverse range of phenomena and applications, frequently in the context of laser applications, owe their means of operation to the properties of the photon. Yet, since the arrival of the

Photons from the Future

What would be the consequences of assuming the existence of antiphotons which propagate backward in time? This is obviously permitted mathematically. There is also physical justification in the

Planck, Photon Statistics, and Bose-Einstein Condensation

The interplay between optical and statistical physics is a rich and exciting field of study. Black body radiation was the first application of photon statistics, although it was initially treated as

Einstein and the quantum theory

This is an account of Einstein's work and thoughts on the quantum theory. The following topics will be discussed: The light-quantum hypothesis and its gradual evolution into the photon concept. Early

Quantum optics, by John Garrison and Raymond Chiao

[2]. Although Planck considered this suggestion more as a calculus aid than an effective description of nature’s behaviour, Albert Einstein (1905) extracted the extreme consequences of Planck’s

The Properties of Light

The mystery of light has formed the core of creation stories in every culture, and attracted the earnest attentions of philosophers since at least the fifth century BCE. Their questions have ranged
