The most famous packing problem concerns spheres. In 1611, the astronomer Johannes Kepler proposed that the densest way to ...

Colloidal halide perovskite nanocrystals have emerged as strong candidates for light-emitting diodes and solar applications ...

We’ve found a clever way to get around this limitation, however, by making matter out of light. In place of the atomic lattice, we use light waves to create what we call an optical lattice.

A new metasurface design greatly improves light emission in atomically thin materials, offering a path to low-power, flexible ...

Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists have developed a new method for connecting particles -- one that could help in the development ...

Lattice light sheet microscopy is a newer light sheet microscopy technique that is primarily used in biological settings. It is a method that uses sheets of light in a lattice conformation to take ...

The technique, which works by optically “shaking” the crystal lattice of dysprosium orthoferrite (DyFeO 3), could form the basis of a fast and energy-efficient new way of processing data. Modern hard ...

Tungsten Photonic Lattice Changes Heat To Light; Cool Tungsten Light Bulb May Be Possible. ScienceDaily . Retrieved May 26, 2025 from www.sciencedaily.com / releases / 2002 / 05 / 020509074556.htm ...

In a perfect atomic crystal, visible light travels ballistically, only occasionally scattering off a lattice atom. As disorder increases — for example, through the introduction of a foreign ...

Deep-sea sponges have a secret: their light lattice-like forms are astonishingly stiff and strong. Inspired by these creatures, RMIT researchers have developed a new structure to make ...

A square lattice light pattern created using holographic masks is projected onto the atom plane through the high resolution objective. The lattice spacing in the atom plane is 640 nm.
