Wavelets and spacetime squeeze

Abstract

It is shown that the wavelet is the natural language for the Lorentz covariant description of localized light waves. 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 (Delta(t))(Delta(w)) is approximately 1 for light waves is a Lorentz-invariant relation. The connection between photons and localized light waves is examined critically.

A new approach to the photon localization problem

D. Han, Y. S. Kim, Marilyn E. Noz

Since wavelets form a representation of the Poincare group, it is possible to construct a localized superposition of light waves with different frequencies in a Lorentz-covariant manner. This localized wavelet satisfies a Lorentz-invariant uncertainty relation, and also the Lorentz-invariant Parseval's relation. A quantitative analysis is given for the difference between photons and localized waves. It is then shown that this localized entity corresponds to a relativistic photon with a sharply defined momentum in the non-localization limit. Waves are not particles. It is confirmed that the wave-particle duality is subject to the uncertainty principle.

Wavelets, windows, and photons

D. Han, Y.S. Kim, Marilyn E. Noz

Within the wavelet framework, it is shown that it is possible to construct a Lorentz-covariant superposition of light waves. The concept of window allows the definition of a “finite difference” between wavelets and photons. It is pointed out that a windowed function is as accurate as any continuous function which may be constructed from a discrete set of experimental data.

Integration of Dirac’s Efforts to Construct a Quantum Mechanics Which is Lorentz-Covariant

Young S Kim, Marilyn E. Noz

The lifelong efforts of Paul A. M. Dirac were to construct localized quantum systems in the Lorentz covariant world. In 1927, he noted that the time-energy uncertainty should be included in the Lorentz-covariant picture. In 1945, he attempted to construct a representation of the Lorentz group using a normalizable Gaussian function localized both in the space and time variables. In 1949, he introduced his instant form to exclude time-like oscillations. He also introduced the light-cone coordinate system for Lorentz boosts. Also in 1949, he stated the Lie algebra of the inhomogeneous Lorentz group can serve as the uncertainty relations in the Lorentz-covariant world. It is possible to integrate these three papers to produce the harmonic oscillator wave function which can be Lorentz-transformed. In addition, Dirac, in 1963, considered two coupled oscillators to derive the Lie algebra for the generators of the O(3,2) de Sitter group, which has ten generators. It is proven possible to contract this group to the inhomogeneous Lorentz group with ten generators, which constitute the fundamental symmetry of quantum mechanics in Einstein’s Lorentz-covariant world.

Covariant phase-space representation for localized light waves

Y. S. Kim, Eugene Paul Wigner

It is suggested that the light-cone coordinate system is the natural language for the Lorentz-covariant phase-space representation of quantum mechanics. The localized light wave is discussed as an illustrative example. It is shown that the unitary transformation of a localized light wave from one Lorentz frame to another can be achieved through its covariant phase-space representation.
