Niels Benedikter

I'm a professor of mathematical physics at the University of Milan (Statale).

The focus of my work is on the mathematically rigorous derivation of effective theories for quantum many-body systems. Examples are the Gross-Pitaevskii and Bogoliubov theories of Bose-Einstein condensates, Hartree-Fock theory for fermionic many-body systems, spin wave theory for the ferromagnetic Heisenberg model, and the random phase approximation describing emergent bosonic excitations in the Fermi gas.

Since August 2025 I also lead the BCAM Severo Ochoa Strategic Lab on Quantum Mathematics at the Basque Center for Applied Mathematics.

Milano is well connected to most of Europe by train, see Seat61.

Within Italy, Milano is most efficiently reached by Trenitalia's Frecciarossa trains or competing Italotreno (similar speed, price, and comfort). Most, but not all, international and all national tickets can be bought on Trainline.

From Belgium, the Netherlands, and Germany (Aachen, Cologne), three times per week you can reach Milano climate-friendly by direct European Sleeper night train.

From France, the main connections are by Trenitalia's Frecciarossa trains and by SNCF's TGV trains. Both can be booked on Trainline.

From Germany, Milano can be reached by day train using the EuroCity trains through Switzerland. Tickets are often cheapest buying a Deutsche-Bahn ticket until "Chiasso", then buying a Trenitalia ticket from Chiasso to Milano Centrale. (You can buy the Trenitalia ticket on the same EuroCity train that brought you to Chiasso, so you don't actually need to change train in Chiasso.)

To reach the mathematics department in Milan, take the green metro line from "Porta Garibaldi" or "Centrale" to the stop "Piola". Exit the metro station toward Piazza Leonardo da Vinci/Politecnico, cross the square and continue straight. About 10 minutes by foot, see OpenStreetMap.

To pay the public transport ticket in Milan, you can just tap your credit card to the gates (metro) or card reader (bus/tram).
