Quantum Formulation of Fractional Orbital Angular Momentum
J. B. Goette, S. Franke-Arnold, R. Zambrini +1
The quantum theory of rotation angles (S. M. Barnett and D. T. Pegg, Phys. Rev. A, 41, 3427-3425 (1990)) is generalised to non-integer values of the orbital angular momentum. This…
Optical ferris wheel for ultracold atoms
S. Franke-Arnold, J. Leach, M. J. Padgett +6
We propose a versatile optical ring lattice suitable for trapping cold and quantum degenerate atomic samples at discrete angular positions. We demonstrate the realisation of intens…
Fourier relationship between angular position and optical orbital angular momentum
Eric Yao, Sonja Franke-Arnold, Johannes Courtial +2
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…
Phase-dependent light propagation in atomic vapors
S. Kajari-Schroeder, G. Morigi, S. Franke-Arnold +1
Light propagation in an atomic medium whose coupled electronic levels form a diamond-configuration exhibits a critical dependence on the input conditions. In particular, the relati…
Large-uncertainty intelligent states for angular momentum and angle
Joerg B. Goette, Roberta Zambrini, Sonja Franke-Arnold +1
The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation…
