Rydberg electromagnetically-induced transparency has been widely studied as a medium supporting light propagation under the action of nonlocal nonlinearities. Recently, optical potentials based on moir\'e lattices (MLs) were introduced for exploring unconventional physical states. Here, we predict possibility creating fully three-dimensional (3D) bullets (LBs) in cold gases ML potentials. The n...

Abstract Efficiently simulating the full range of light effects in arbitrary input scenes that contain participating media is a difficult task. Unified points, beams and paths (UPBP) an algorithm capable capturing wide effects, by combining bidirectional path tracing (BPT) photon density estimation (PDE) with multiple importance sampling (MIS). A computationally expensive task UPBP MIS weight c...

For the measurement of surfaces of close range objects, which do not show sufficient surface texture, an automatic system based on the projection of structured light has been developed. An off-the-shelf slide projector projects chromium slides with a regular dot pattern of 800 ... 8000 dots and perfectly binary transparency characteristics onto a surface. For robust point determination the obje...

A robust light storage and retrieval (LSR) in high dimensions is highly desirable for light and quantum information processing. However, most schemes on LSR realized up to now encounter problems due to not only dissipation, but also dispersion and diffraction, which make LSR with a very low fidelity. Here we propose a scheme to achieve a robust storage and retrieval of weak nonlinear high-dimen...
