Atomic-Scale Dynamics Probed by Photon Correlations

2021-02-12T10:08:07+01:00Tags: , , , |

Authors: Roslawska, Anna; Leon, Christopher C.; Grewal, Abhishek; Merino, Pablo; Kuhnke, Klaus; Kern, Klaus Contribution: Article Journal: ACS NANO Publication date: 2020/06/23 DOI: 10.1021/acsnano.0c03704 Abstract: Light absorption and emission have their origins in fast atomic-scale phenomena. To characterize these basic steps (e.g., in photosynthesis, luminescence, and quantum optics), it is necessary to access picosecond temporal and [...]
