Symmetries of the Poincare sphere and decoherence matrices
S. Baskal, Y. S. Kim
The Stokes parameters form a Minkowskian four-vector under various optical transformations. As a consequence, the resulting two-by-two density matrix constitutes a representation o…
Harmonic Oscillators as Bridges between Theories: Einstein, Dirac, and Feynman
Y. S. Kim, Marilyn E. Noz
Other than scattering problems where perturbation theory is applicable, there are basically two ways to solve problems in physics. One is to reduce the problem to harmonic oscillat…
Feynman's Branes and Feynman's Oscillators
Y. S. Kim, Marilyn E. Noz
Based on Feynman's lifetime efforts on quantum mechanics and relativity, it is concluded that the basic difference between field theory and string theory is that field theory is ba…
Lorentz Group in Ray Optics
S. Baskal, E. Georgieva, Y. S. Kim +1
It has been almost one hundred years since Einstein formulated his special theory of relativity in 1905. He showed that the basic space-time symmetry is dictated by the Lorentz gro…
Wigner's new physics frontier: Physics of two-by-two matrices, including the Lorentz group and optical instruments
Sibel Baskal, Elena Georgieva, Y. S. Kim
According to Eugene Wigner, quantum mechanics is a physics of Fourier transformations, and special relativity is a physics of Lorentz transformations. Since two-by-two matrices wit…
Is the concept of quantum probability consistent with Lorentz covariance?
Y. S. Kim, Marilyn E. Noz
Lorentz-covariant harmonic oscillator wave functions are constructed from the Lorentz-invariant oscillator differential equation of Feynman, Kislinger, and Ravndal for a two-body b…
