When laser energy is deposited in a target material, numerous complex processes take place at length and time scales that are too small to visually observe. To study and ultimately fine-tune such ...

Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

One of the defining breakthroughs that set quantum physics apart from classical physics was the realization that matter behaves very differently at ...
