A team of researchers from the University of Shanghai for Science and Technology and the University of Dayton has developed a way to bend light into a vortex ring using mirrors, lasers and lenses. This diagram also indicates the degeneracy of each level, the degener- acy of an energy level being the number of independent eigenfunctions associ- ated with the level. Operator methods are very useful both for solving the Harmonic Oscillator problem and for any type of computation for the HO potential. No previous knowledge of linear differential equation theory or Fourier analysis are required, but rather only a few mw.
