Rydberg atoms are excited atoms that contain one or more electrons with a high principal quantum number. Due to their large size, long-range dipole-dipole interactions and strong coupling to external fields, these atoms have ...
Rydberg atoms, which are atoms in a highly excited state, have several unique and advantageous properties, including a particularly long lifetime and large sensitivities to external fields. These properties make them valuable ...
Rydberg molecules are giant molecules made up of tens or hundreds of atoms bound to a Rydberg atom. These molecules have a permanent dipole (i.e., a pair of oppositely charged or magnetized poles), as one of their atoms is ...
Using lasers, U.S. and Austrian physicists have coaxed ultracold strontium atoms into complex structures unlike any previously seen in nature.

What is inside an atom between the nucleus and the electron? Usually there is nothing, but why could there not be other particles too? If the electron orbits the nucleus at a great distance, there is plenty of space in between ...

(Phys.org) —Researchers working at the French National Center for Scientific Research have for the first time, directly measured the Van der Waals force between two atoms. In their paper published in the journal Physical ...
In an achievement that could help enable fast quantum computers, University of Michigan physicists have built a better Rydberg atom trap. Rydberg atoms are highly excited, nearly-ionized giants that can be thousands of times ...

(PhysOrg.com) -- When Enrico Fermi investigated the Rydberg atom in the '30s, he never imagined that the giant atoms could form molecules. Later, in the '70s and '80s, theoretical physicist Chris Greene predicted that Rydberg ...
