In the early 1920s, physicists were first working out the mysteries of the quantum Universe. Particles sometimes behaved as waves, with indeterminate positions, momenta, energies, and other properties ...

In Rydberg atoms, at least one electron is excited to a state with a high principal quantum number. In an ultracold environment, this low-energy electron can scatter off a ground state atom allowing ...

Rice's Shuzhen Ye puts an electron into a Trojan orbit The atom may not be a planetary system, but under specific circumstances it can behave like one. That is the curious finding of physicists in ...
