The Rydberg state is widespread in a variety of physical platforms such as atoms, molecules, and solids. In particular, Rydberg excitons are highly excited Coulomb-bound states of electron-hole pairs, ...

Realizing efficient light–matter interfaces and engineering states of light at the quantum level are challenging due to the small interaction cross section between atoms and photons 1. Overcoming this ...

Rydberg Matter From Leif Holmlid’s webpage: Rydberg Matter is a state of matter of the same status as liquid or solid, since it can be formed by a large number of atoms and small molecules. So far, it ...

Using lasers, U.S. and Austrian physicists have coaxed ultracold strontium atoms into complex structures unlike any previously seen in nature. "I am amazed that we've discovered a new way that atoms ...

Rydberg atom array experiments have demonstrated the ability to act as powerful quantum simulators, preparing strongly-correlated phases of matter which are challenging to study for conventional ...

Making a connection: An artist's impression of a Rydberg atom bonded to an ion. (Courtesy: Danyel Cavazos) A novel type of molecule that is longer than some kinds of bacteria has been detected by ...

Scientists have provided proof for a new state of matter: an electron orbits a nucleus at a great distance, while many other atoms are bound inside the orbit. What is inside an atom, between the ...

Exotic, ultracold states of matter are challenging physicists to draw on expertise from atomic, condensed-matter and plasma physics, and causing a few surprises along the way The ultracold world has ...

A team of scientists has described how a new state of matter can be created, by essentially putting atoms inside other atoms. The rest of this article is behind a paywall. Please sign in or subscribe ...

Scientists have observed a new class of quantum matter at the very smallest scales in one of the coldest environments ever made. This discovery could pave the way for new technologies including ...

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 ...
