Description
Very strong electromagnetic fields can induce electron-positron pair creation predicted by quantum electrodynamics. A possible way to demonstrate it is via the multiphoton Breit-Wheeler process in strong laser fields. The challenge in this setup is to hold seed particles in the hot-spot region of the reaction. This method using radially polarised laser pulses to trap seed electrons is studied in M. Jirka and S. Bulanov, PRL 133 125001 (2024). We simulate this process in the PIC code SMILEI (https://smileipic.github.io/Smilei/), which contains the respective models. The further advancement in this field is planned in Project OPEN-34-69. This project will consist of designs of more advanced optical traps. To reach this goal, we need implement some new features in the SMILEI code.
This poster details the simulations and methods, it also provides perspective for forthcoming studies.
