Optical angular-momentum flux*
We introduce the angular-momentum flux as the natural description of the angular momentum carried by light. We present four main results: (i) angular-momentum flux is the flow of angular momentum across a surface and, in conjunction with the more familiar angular-momentum density, expresses the conservation of angular momentum. (ii) The angular-momentum flux for a light beam about its axis (or ...
متن کاملOptical orbital angular momentum.
We present a brief introduction to the orbital angular momentum of light, the subject of our theme issue and, in particular, to the developments in the 13 years following the founding paper by Allen et al. (Allen et al. 1992 Phys. Rev. A 45, 8185 (doi:10.1103/PhysRevA.45.8185)). The papers by our invited authors serve to bring the field up to date and suggest where developments may take us next...
متن کاملAngular Momentum of Supersymmetric Cold Rydberg Atoms.
Semiunitary transformation is applied to discuss supersymmetrization of cold Rydberg atoms. In the limit of vanishing kinetic energy the lowest angular momentum of the supersymmetric cold Rydberg atom is 3h̄/2. A possible experimental verification is suggested. [S0031-9007(96)00109-3] PACS numbers: 32.80.Rm, 11.30.Pb Recently Baxter [1] showed that cold Rydberg atoms can play an interesting role...
متن کاملFourier relationship between angular position and optical orbital angular momentum.
We demonstrate the Fourier relationship between angular position and angular momentum for a light mode. In particular we measure the distribution of orbital angular momentum states of light that has passed through an aperture and verify that the orbital angular momentum distribution is given by the complex Fourier-transform of the aperture function. We use spatial light modulators, configured a...
متن کاملAngular-momentum-state distribution of sodium atoms photoassociated in a magneto-optical trap
The study of ultracold collisions between groundand excited-state atoms has received a great deal of attention @1#. Trap-loss measurements have revealed hyperfine@2# and fine-structure-changing collisions @3#, the rich detail of ultracold photoassociative spectroscopy has provided important information about long-range atom-atom interaction potentials @4#, and intensity and time-resolved studie...
