We investigate the separation of the total angular momentum J of the electromagnetic field
into a ‘spin’ part S and an ‘orbital’ part L. We show that both ‘spin’ and ‘orbital’ angular …

We consider the separation of the total angular momentum of the electromagnetic field into a"
spin" and an" orbital" part. Though this separation is normally considered to be unphysical …

The propagation of light beams through astigmatic lens systems is accompanied by a transfer
of orbital angular momentum. We develop a method to describe propagating light beams …

The operator algebra of the quantum harmonic oscillator is applied to the description of
Gaussian modes of a laser beam. Higher-order modes of the Hermite-Gaussian or the Laguerre-…

Intense light can exert a mechanical action on the motion of atoms in two quite distinct ways.
The resonance radiation force is based upon the exchange of photon momentum between …

We calculate the reflection coefficient for a light beam incident on the interface between a
dielectric and a resonant atomic vapor to first order in the dipole polarization in the vapor. The …

A one-dimensional fluid model for radio-frequency glow discharges is presented which
describes silane/hydrogen discharges that are used for the deposition of amorphous silicon ( a -…

The orbital angular momentum inherent to light beams with a helical wavefront can be
transferred to non-isotropic lenses. A system of three cylindrical lenses suffices to transform an …

In the literature two different simplified expressions exist for the spontaneous emission factor
β, being the fraction of spontaneous emission radiated into a specific optical mode. These …

We propose a novel setup to investigate the entanglement of orbital angular momentum states
living in a high-dimensional Hilbert space. We incorporate noninteger spiral phase plates …
