Adrien Leblanc partner in an ERC Synergy grant
Adrien Leblanc of the UPX group is one of the partners of the recently awarded ERC Synergy grant 2025 “Probing the non-perturbative regime of Quantum Electrodynamics with extreme light” (NP-QED).
Together with an international consortium made up of CEA Saclay (FR), DESY (GER) and the University of Rochester (USA), he will develop experiments to test the predictions of Quantum Electrodynamics (QED) in yet unexplored regimes of extremely high light intensity that turn the vacuum itself into a nonlinear medium.
This lets him continue his work started thanks to the ERC Starting grant EXAFIELD.

Numerical simulation (WarpX code) of the collision of a high-power laser amplified by a plasma mirror (red/blue) with a relativistic electron beam produced by a laser-plasma accelerator (grey), in the unexplored strong-field regime of QED. This collision generates intense signatures involved in this regime: high-energy 𝛾 photons (lines) and relativistic electron-positron pairs (dots), which we seek to detect in this project.
