In the media. Quantum physics: exceptional measurement of 'Rabi oscillations' using the FERMI laser
|
The results of the experiment published in Nature. This and the great potential of Free Electron Lasers are being discussed at the ongoing FEL2022 International Conference in Trieste, which closes on 26 August
The periodic pattern with which the electrons of atoms exchange energy with laser radiation has been known since the theory was first presented in 1955 by Autler and Townes. The phenomenon, referred to as 'Rabi oscillations', has since then been experimentally observed in the most diverse areas of physics, but only for long-wavelength radiation, and this is still a key observation in understanding radiation-matter interaction. |
The article, published on 17 August, with Saikat Nandi of the Lumiere Matiere Institute in Lyon as first author, involved 29 researchers from Italy, France, Sweden and Germany. The high-intensity laser pulses required for the experiment were generated by the FERMI free-electron laser at the Elettra Sincrotrone Trieste research centre. The conference, which was postponed last year due to the pandemic, this year celebrates its 40th edition and the arrival of around 300 participants including researchers and related companies from all over the world. Organised and promoted by Elettra Sincrotrone Trieste, at the helm of which Prof. Alfonso Franciosi, President and CEO, has been firmly during these important years of development, the conference not only provides intense days of scientific discussion, but also allows 150 of the best scientists working in other similar institutes to visit FERMI, to grasp the technical specificities and innovations that make it unique in terms of the purity of the light produced. Trieste and its system are once again confirmed as being at the top of the world in terms of scientific research, the number of projects and publications, and the ability to attract the best brains of the future. |
