Description
Understanding nonperturbative regimes in Strong-Field Quantum Electrodynamics (SFQED) is essential for exploring fundamental processes in high-intensity laser-matter interactions. Despite significant progress in analyzing the Schwinger model, a systematic comparison of the underlying frameworks remains incomplete. In particular, direct contrasts between U(1) and Zₙ models within standard lattice gauge QED, as well as bridging the gap to the semi-classical kinetic approach to Schwinger pair production, remain largely underexplored.
Here, we present a parametric exploration of the validity regimes of various SFQED approaches focusing on Schwinger pair-production rate and its connections to related processes. This poster highlights preliminary results from these studies, advancing our understanding of SFQED and informing future theoretical and computational strategies.
