Optical activities as computing resources for space–time symmetries

Y.S. Kim
2010 Journal of Modern Optics  
It is known that optical activities can perform rotations. It is shown that the rotation, if modulated by attenuations, can perform symmetry operations of Wigner's little group which dictates the internal space-time symmetries of elementary particles.
