A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly ...

Towards Power-Efficient Depth-Resolved Reflective Single-Pixel THz Imaging with Prism-Based TIR Modulation

Abstract: We introduce a prism-based reflective architecture for single-pixel terahertz (THz) imaging that removes the 6 dB power penalty imposed by the standard 50/50 beam splitter and raises the ...

Efficient Detection of Non-Lambertian Reflectance Behavior and Lambertian Surface Characterization Using Minimal Angular Sampling in Light Fields

This paper presents a method for classifying Lambertian, Non-Lambertian, and Partial Lambertian surfaces in light field data by extracting angular variance features from multiple views of 3D scenes.
