The ability to describe the internal structure of atoms is important not only for understanding the composition of matter, but also for designing new experiments to explore fundamental physics.

You've probably seen videos showing characters walking through walls like ghosts. Upon closer inspection, atoms consist of a vast majority of empty space. So why is physical reality so different?

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...
