Many-Body physics at and out-of equilibrium

Shanghai (China), 2026, 2 November

The standard Hamiltonian in electronic structure calculations does not explicitly include the transverse electromagnetic interactions outside its explicit description.

In this talk Andrea Marini will introduce the transverse matter Hamiltonian, a low energy gauge-invariant extension that incorporates these interactions without resorting to the full machinery of quantum electrodynamics.

It will be discussed how this framework opens new avenues for studying optical adsorption, magnetic phenomena and interactions involving electronic and phononic currents, broadening the theoretical tools available to describe the electromagnetic properties of materials.

The talk will be hosted by the Key Laboratory of Computational Physical Sciences of the Fudan University in Shanghai, on November 2026, the 2nd.

Following the previous Quantum Mechanics (basic and advanced) courses that the APhRICA project has been delivering since 2024 at the UR University of Rwanda (Kigali) and TU-K Technical University of Kenya (Nairobi), this edition of the Many-Body course marked a significant step forward.
Indeed, this second edition focused on training the lecturers recruited for the 2025–2027 cycle.

Lecturers from various universities in Rwanda, Kenya, and Uganda, who had previously completed the QM1 and DM2 preparatory courses starting in December 2025, delved into world-class quantum physics by attending the “Many Body 1” course hosted by ICTP-EAIFR in Kigali from September 28 to October 9. They will continue their training this coming November with the advanced “Many Body 2” course and will conclude the cycle in 2027 by taking the DFT course.

The importance of this event lies in the fact that the university lecturers are now trained so they can cascade this knowledge to their classes distributed across East African universities.

And this represents a crucial milestone for the full achievement of the strategic objective of the APhRICA second-cycle training plan: lecturers will transfer the knowledge they have acquired to the next African generation!

As the previous editions, starting from 2020, also this year Elsevier has published the database of top-cited scientists that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator (c-score).

In the paper “August 2026 data-update for Updated science-wide author databases of standardized citation indicators” the Contributor (John P.A. Ioannidis, Stanford University) classifies scientists into 20 scientific fields and 174 sub-fields (Science-Metrix classification). Field- and subfield-specific percentiles are also provided for all scientists with at least 5 papers. Career-long data are updated to end-of-2025 and single recent year data pertain to citations received during calendar year 2025. The selection is based on the top 100,000 scientists by c-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field. This version (9) is based on the August 1, 2026 snapshot from Scopus, updated to end of citation year 2025. Calculations were performed using all Scopus author profiles as of August 1, 2026. The c-score focuses on impact (citations) rather than productivity (number of publications) and it also incorporates information on co-authorship and author positions (single, first, last author).
