# The Quantum Theory of the Emission and Absorption of Radiation

@article{Dirac1927TheQT, title={The Quantum Theory of the Emission and Absorption of Radiation}, author={Paul Adrien Maurice Dirac}, journal={Proceedings of The Royal Society A: Mathematical, Physical and Engineering Sciences}, year={1927}, volume={114}, pages={243-265} }

The new quantum theory, based on the assumption that the dynamical variables do not obey the commutative law of multiplication, has by now been developed sufficiently to form a fairly complete theory of dynamics. One can treat mathematically the problem of any dynamical system composed of a number of particles with instantaneous forces acting between them, provided it is describable by a Hamiltonian function, and one can interpret the mathematics physically by a quite definite general method…

Recent developments in the theory of radiation have brought this subject to a very complete state. There is a nearly closed domain, in which the interaction between charged particles and the…

### The concept of the photon

- Physics
- 1972

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…

### Nothing's plenty. The vacuum in modern quantum field theory

- Physics
- 1985

Abstract In contemporary theories of the structure of matter at very short distance scales, various properties (some of them hypothetical as yet) of the vacuum are of crucial importance. The…

### Classical limit of the interaction of a quantum system with the electromagnetic field
