SUMMARY
The Schwinger effect, which refers to the production of electron-positron pairs from a vacuum under strong electric fields, has not been conclusively observed or proven. Discussions highlight the challenges in experimentally accessing this phenomenon, particularly in relation to e+e- pair production by focused laser pulses and the pulsations of electron-positron plasma in optical laser fields. Historical references, including Phys Rev D 2, 7, 1191 (1970) by Itzykson and Brezin, emphasize the lack of detection for related phenomena such as photon-photon scattering, which arises from virtual pair creation. Ongoing research efforts are focused on achieving experimental validation of the Schwinger effect.
