Paper on ultrastrong atom-field interactions in Nature Physics

Our paper, Ultrastrong coupling of a single artificial atom to an electromagnetic continuum in the nonperturbative regime, was accepted in Nature Physics and has appeared as an advanced online publication on October 10, 2016. A News and Views article by Kater Murch discusses our result and two related papers on superconducting artificial atoms in interaction with a cavity and a photonic crystal respectively. See also this news article discussing this result. Congratulations to Pol and the others for this work!
