Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly ...

Quantum computers of the future could operate via the energy transitions of excited atoms, or even from pure light, if a rapidly growing area of atomic physics continues to meet with success, writes ...

The possibility to exactly solve quantum mechanical problems such as the hydrogen atom is based on the existence of symmetries from which constants of motion arise, reducing the degrees of freedom and ...
