Next Wednesday I will give an official Colloquium talk in the Physics and Materials Science Research Unit at the University of Luxembourg.

It will be an exciting chance to give an introductory and didactic review of the Ultrafast science.


Nature Communication on Diamondoids

The development of theories and methods devoted to the accurate calculation of the
electronic quasi-particle states and levels of molecules, clusters and solids is of prime
importance to interpret the experimental data. These quantum systems are often modelled by
using the Born–Oppenheimer approximation where the coupling between the electrons and
vibrational modes is not fully taken into account, and the electrons are treated as pure quasi-
particles. Here, we show that in small diamond cages, called diamondoids, the electron–
vibration coupling leads to the breakdown of the electron quasi-particle picture. More
importantly, we demonstrate that the strong electron–vibration coupling is essential to
properly describe the overall lineshape of the experimental photoemission spectrum. This
cannot be obtained by methods within Born–Oppenheimer approximation. Moreover, we
deduce a link between the vibronic states found by our many-body perturbation theory
approach and the well-known Jahn–Teller effect.
