Description
Millicharged particles with tiny electric charge $q_\chi$ have garnered significant attention due to their profound implications for physics beyond the Standard Model. In this talk, I will present a direct laboratory search for such particles via Schwinger pair production using correlated quantum sensors. In the low-mass regime below $4.0 \times 10^{-5}$ eV, our approach provides a model-independent constraint on the charge of millicharged fermions down to $\epsilon\equiv q_\chi/e \approx 1.7 \times 10^{-7}$, surpassing existing Schwinger-based laboratory limits by nearly one order of magnitude.
