The O(3,2) Symmetry derivable from the Poincaré Sphere
Y. S. Kim
Henri Poincaré formulated the mathematics of the Lorentz transformations, known as the Poincaré group. He also formulated the Poincaré sphere for polarization optics. It is noted t…
Historical Approach to Physics according to Kant, Einstein, and Hegel
Y. S. Kim
It is known that Einstein's conceptual base for his theory of relativity was the philosophy formulated by Immanuel Kant. Things appear differently to observers in different frames.…
Feynman and Squeezed States
Y. S. Kim
In 1971, Feynman et al. published a paper on hadronic mass spectra and transition rates based on the quark model. Their starting point was a Lorentz-invariant differential equation…
QCD's Partner needed for Mass Spectra and Parton Structure Functions
Y. S. Kim
As in the case of the hydrogen atom, bound-state wave functions are needed to generate hadronic spectra. For this purpose, in 1971, Feynman and his students wrote down a Lorentz-in…
Possible Minkowskian Language in Two-level Systems
Y. S. Kim
One hundred years ago, in 1908, Hermann Minkowski completed his proof that Maxwell's equations are covariant under Lorentz transformations. During this process, he introduced a fou…
Diagonalization of Sp(2) matrices
S. Baskal, Elena Georgieva, Y. S. Kim
The two-by-two Sp(2) matrix has three parameters with unit determinant. Yet, there are no established procedures for diagonalizing this matrix. It is shown that this matrix can be…
