TL;DR: An optical process in which the spin angular momentum carried by a circularly polarized light beam is converted into orbital angular momentum, leading to the generation of helical modes with a wave-front helicity controlled by the input polarization is demonstrated.

TL;DR: Bomzon et al. as discussed by the authors presented a Pancharatnam-Berry phase optical element for wave front shaping in the visible spectral domain, based on patterned liquid crystal technology, with the possibility of electro-optically switching between opposite helicities by controlling the handedness of the input circular polarization.

TL;DR: In this paper, a photonic implementation of the quantum walk in the orbital angular momentum space of light is presented, where the whole process develops in a single light beam, with no need of interferometers, and it requires optical resources scaling linearly with the number of steps.

TL;DR: This work studies hydrated model membranes, consisting of stacked bilayers of 1,2-dioleoyl-sn-glycero-3-phosphocholine lipids, using terahertz time-domain and infrared spectroscopy to elucidate how the interplay between the model membrane and water molecules results in different water dynamics.
