Wigner's Space-time Symmetries based on the Two-by-two Matrices of the Damped Harmonic Oscillators and the Poincaré Sphere
Sibel Baskal, Young S. Kim, Marilyn E. Noz
The second-order differential equation for a damped harmonic oscillator can be converted to two coupled first-order equations, with two two-by-two matrices leading to the group $Sp…

Entropy and Temperature from Entangled Space and Time
Young S. Kim, Marilyn E. Noz
Two coupled oscillators provide a mathematical instrument for solving many problems in modern physics, including squeezed states of light and Lorentz transformations of quantum bou…

Poincaré Sphere and a Unified Picture of Wigner's Little Groups
Y. S. Kim
It is noted that the Poincaré sphere for polarization optics contains the symmetries of the Lorentz group. The sphere is thus capable of describing the internal space-time symmetri…
