Physicists in Darmstadt have been able to stop something that has the greatest possible speed and that never really stops. We're talking about light. Already a decade ago, physicists stopped it very for a short moment. In ...

One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. Instead, quantum physics ...

The debate over the mechanism that causes superconductivity in a class of materials called the pnictides has been settled by a research team from Japan and China. Superconductivity was discovered in the pnictides only recently, ...

(Phys.org) —Charles Radin a mathematical physicist with the University of Texas and one of his former student's David Aristoff, have built a 2D model material made of disks to represent atoms. In their article published ...
A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain ...

(Phys.org) —Material design usually follows what is known as the Edisonian method, a traditional process characterized by trial-and-error discovery rather than a systematic theoretical approach. While this may be somewhat ...
For half a century, researchers have seen loops of displaced atoms appearing inside nuclear reactor steel after exposure to radiation, but no one could work out how.

In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a motif, a set of atoms arranged in a particular way, and a lattice. Motifs are located upon the points of a lattice, which is an array of points repeating periodically in three dimensions. The points can be thought of as forming identical tiny boxes, called unit cells, that fill the space of the lattice. The lengths of the edges of a unit cell and the angles between them are called the lattice parameters. The symmetry properties of the crystal are embodied in its space group. A crystal's structure and symmetry play a role in determining many of its properties, such as cleavage, electronic band structure, and optical properties.
