Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

(Nanowerk News) Molecules are so small that we cannot even see them with ordinary microscopes. This makes studying molecules or chemical reactions difficult: researchers are limited to either indirect ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Nearly all computer models of molecules and materials are based on density functional theory (DFT) approximations. These methods help efficiently simulate the structure, energy, and properties of ...

New insights into a popular and potentially useful model of how electrons behave in solids have been provided by an experiment involving ultracold atoms. Markus Greiner and colleagues at Harvard ...

An international group of researchers, working on complex computer models for predicting the behavior of electrons, has discovered that those very computational models might not be as accurate as they ...

One of the great unanswered question in biology is why organisms have evolved to cooperate. The long-term benefits of cooperation are clear—look at the extraordinary structures that termites build, ...
