Abstract We investigate electron-positron pair production in frequency-chirped, polarized laser fields using the Dirac-Heisenberg-Wigner formalism. A key theoretical finding is the polarization-dependent critical chirp threshold $b_{\rm c}(\delta)$, which marks the transition between tunneling-dominated and multiphoton pair production regimes: $b_{\rm c}$ doubles as polarization evolves from linear ($\delta=0$, $b_{\rm c}(0)=0.02 {\rm m}^2$) to circular ($\delta=1$, $b_{\rm c}(1)=0.04 {\rm m}^2$). Above this threshold, chirp induces spectral compression with the momentum distribution width scaling as $\Delta q \propto b^{-1/2}$, concentrating pairs into a smaller phase-space volume and enhancing production yields by up to three orders of magnitude, following the universal scaling law $n \propto (b\tau)^{3/2}$. Notably, non-monotonic polarization dependence is observed at intermediate chirp values, where linear polarization temporarily surpasses circular in yield before convergence at large $b$. These results establish chirp as a precise control parameter for optimizing EP pair production in nonperturbative quantum electrodynamics, advancing the theoretical framework for understanding quantum vacuum dynamics and providing a foundation for structured pulse engineering in strong-field quantum electrodynamics.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
