First-ever evidence for creation of matter by electric field

A break-trough article providing first-ever evidence for the reality of the Schwinger effect: the creation of electrons (and corresponding holes) from "nothing" under strong electric field influence in graphene superlattices: Science 2022, vol. 375, no. 6579, "Out-of-equilibrium criticalities in graphene superlattices" https://www.science.org/doi/abs/10.1126/science.abi8627
