LPHYS'26.    Program:

Seminar 9: Extreme Light Technologies, Science, and Applications

Co-chairs:

Our seminar aims at covering the theoretical and experimental advances related to high-field physics, the extreme existing multi-petawatt and prospected light facilities and associated applications. This includes topics like the study of extreme laser acceleration, quantum radiative reaction, pair production and spin dynamics, as well as laboratory astrophysics and the search for new physics with ultrastrong laser pulses and state-of-the-art high-energy leptons beams.
