Description:
Electronically highly excited (Rydberg) atoms experience quantum state-changing interactions similar to Forster processes found in complex molecules, offering a model system to study the nature of dipole-mediated energy transport under the influence of a controlled environment. We demonstrate a nondestructive imaging method to monitor the migration of electronic excitations with high time and spatial resolution, using electromagnetically induced transparency on a background gas acting as an amplifier. The continuous spatial projection of the electronic quantum state under observation determines the many-body dynamics of the energy transport.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gunter, G -- Schempp, H -- Robert-de-Saint-Vincent, M -- Gavryusev, V -- Helmrich, S -- Hofmann, C S -- Whitlock, S -- Weidemuller, M -- New York, N.Y. -- Science. 2013 Nov 22;342(6161):954-6. doi: 10.1126/science.1244843.
