Optical Physics: Frontmatter

TL;DR: In this paper, a review of the physics of cold atomic gases in the presence of disorder is presented, with a focus on theoretical developments, although several experiments are also briefly discussed.

TL;DR: A wave-optical shading model based on non-paraxial scalar diffraction theory that is capable of recreating the overall appearance as well as characteristic detail effects observed on real-world examples.

TL;DR: A mechano-optical transduction principle that can allow the encoding of information related to an externally applied mechanical stimulus, e.g., contact, pressure and shape of contact is described.

TL;DR: In this paper, an ultrathin graphene metascreen that possesses dispersive optical activity in the early terahertz spectrum is presented. And the authors show via full-wave simulations that the dichroic metasreen supports perfect linear-to-circular polarization conversion (circular dichroism) in two adjacent tera-hertz frequency bands.
