It has to do with something called "atomic excitation." From the article (emphasis added): When photons pass through a medium ...
For the last seven years, the study authors have been studying atomic excitation, a phenomenon that occurs as a result of interaction between light and matter. During atomic excitation ...
Researchers are exploring multi-level atomic interactions to enhance quantum entanglement. Using metastable states in ...
Interactions between atoms and light rule the behavior of our physical world, but at the same time, can be extremely complex.
Recent studies have employed sophisticated computational methods to explore atomic properties, excitation energies, and transition rates, providing valuable insights into the fundamental physics ...
