Nairobi (Kenya), 2026, 30 June – 10 July

The 2026 training in Nairobi supported under the APhRICA (Advanced Physics Research in Collaboration with Africa) program took place in the first two weeks of July, hosted by TU-K.

Speaking during an interview, Prof. George Amollo, the Dean, Faculty of Applied Sciences and Technology, said the initiative is part of a long-term effort to build home-grown scientific expertise capable of driving innovation across the continent: “For many years, Africa has looked to Europe and America for technological direction. What we are doing now is transferring knowledge so that our researchers develop these capabilities here at home. The new generation should have the skills to create solutions for Africa instead of depending on others”.

The training, delivered to two cohorts, brought together participants from Eastern Africa, with additional researchers joining virtually from other African countries.

The DFT (Density Functional Theory) course was held by Matteo Gatti (CNRS) and the MB (Many Body Perturbation Theory) course was held by Andrea Marini.

PNGF9 Progress of Non-Equilibrium Green’s functions – 9th edition

By in NEWS, Talks Tag ,

Villigen (Switzerland), 2026, 23-27 August

The 9th installment of the Progress of Non-Equilibrium Green’s functions (PNGF9) conference will take place at the Paul Scherrer Institute (PSI) in Switzerland.

The conference aims to bring together researchers directly involved in development and application of non-equilibrium Green’s functions (NGF) methods, as well as young researchers, who address recent developments, current challenges and future perspectives. PNGF9 will bridge theory developments, algorithmic and computational advances, ab-initio approaches, and modeling experiments at large-scale research facilities.

 

 

Frontiers in Ultrafast Phenomena in Quantum Materials

The time–resolved angle–resolved photoemitton spectra of WSe, a paradigmatic metal dichalcogenide, is dominated by a peak that, initially observed withing the gap at the  valley, scatters, on an ultra–fast time scale of  fs to the S valley.
In his talk on April 24 at INFN Frascati National Laboratories, Andrea Marini questioned the commonly used interpretation of the experimental observations in terms of a massive bound electron–hole exciton scattering with phonon and behaving as a quasi–particle. By using a combined theoretical and experimental investigation he demonstrated that the observed dynamics can be interpreted as the photo–induced transition from a direct to and indirect excitonic insulating phase. The peaks that appear in the experimental spectrum correspond to single–particle levels renormalized by the excitonic spontaneous polarization.
