Integration of Dirac's Efforts to construct Lorentz-covariant Quantum Mechanics
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 in…
Poincaré Symmetry from Heisenberg's Uncertainty Relations
Sibel Baskal, Young S. Kim, Marilyn E. Noz
It is noted that the single-variable Heisenberg commutation relation contains the symmetry of the group which is isomorphic to the Lorentz group applicable to one time-like…
Photons in the Quantum World
Sibel Baskal, Young S. Kim, Marilyn E. Noz
Einstein's photo-electric effect allows us to regard electromagnetic waves as massless particles. Then, how is the photon helicity translated into the electric and magnetic fields…
Loop Representation of Wigner's Little Groups
Sibel Baskal, Young S. Kim, Marilyn E. Noz
Wigner's little groups are the subgroups of the Lorentz group whose transformations leave the momentum of a given particle invariant. They thus define the internal space-time symme…
Lorentz Coherence and the Proton Form Factor
Young S. Kim
The dipole cutoff behavior for the proton form factor has been and still is one of the major issues in high-energy physics. It is shown that this dipole behavior comes from the coh…
Lorentz Harmonics, Squeeze Harmonics, and their Physical Applications
Young S. Kim, Marilyn E. Noz
Among the symmetries in physics, the rotation symmetry is most familiar to us. It is known that the spherical harmonics serve useful purposes when the world is rotated. Squeeze tra…
