Schwinger pair production at nonzero temperatures or in compact directions

Electric fields may decay by quantum tunneling: as calculated by Schwinger, an electron-positron pair may be summoned from the vacuum. In this paper, I calculate the pair-production rate at nonzero temperatures. I find that, at high temperatures, the decay rate is dominated by a new instanton that i...
