Figure 2: Capillary transmission at 5 TW peak input power versus time of arrival of the laser pulse after the onset of the discharge, and mode profiles of the input and output laser beam at 40 TW peak ...

The electron, against predictions, appears to be perfectly round, raising questions about one of the fundamental building blocks of the universe. An electron's shape refers to that of the cloud of ...

In 1998 scientists Richard Bader and Carlo Gatti proposed a mathematical model, describing the distribution of delocalized electrons in molecules. Now new research is the first to confirm the accuracy ...

A newly published article in Physical Review Letters eliminates one of the top unsolved theoretical problems in chemical physics as ranked by the National Research Council in 1995. Scientists now can ...

In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...
