One Atom to Rule Them All: A New Class of Quantum Matter Observed

In a recent joint theory/experimental effort, the first Rydberg polaron has been realized in a quantum boson gas. This work observes the formation of exotic oligomeric Rydberg molecules (dimer, trimer, tetramer, pentamer, ...) in a lego construction to many-body Rydberg polarons. The theory was led at ITAMP by Richard Schmidt, Hossein Sadeghpour and Eugene Demler in Physics. https://www.cfa.harvard.edu/news/2018-03.
