Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...

This image shows interference patterns created by surface phonon polaritons propagating across atom-thin layers of crystalline boron nitride and reflecting back from edges. The center image is a model ...

Conventional light microscopy has been instrumental for the study of cells and microorganisms; fluorescence microscopy has enabled visualization of even smaller cell features by selectively adding ...
