These days, everybody learns in grade school that an atom looks a bit like a little solar system, with a positively charged nucleus orbited by negatively charged electrons. Hydrogen is the simplest ...

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists ...

A quantum dot is usually charged by inserting electrons. But electrons can also be removed from a neutral dot. Unexpectedly, positively charged dots are different from highly charged negative ones, ...
