Phys.org  December 23, 2020 An international team of researchers (USA – University of Pittsburgh, Pittsburgh, Japan, Taiwan) trapped surface plasmon polaritons of green light and imaged their propagation on a silver surface at the speed of light so that the light waves came together from two sides to form a light vortex. They took electron microscope images of the emitted electrons to make a snapshot. The light vortex fields can potentially cause transitions in the quantum mechanical phase order in solid state materials, such that the transformed material structure and its mirror image cannot be superimposed. In other words, the […]
