# Schwinger pair production at nonzero temperatures or in compact directions

@article{Brown2015SchwingerPP, title={Schwinger pair production at nonzero temperatures or in compact directions}, author={Adam R. Brown}, journal={Physical Review D}, year={2015} }

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 involves both thermal fluctuation and quantum tunneling; this decay is exponentially faster than the rate in the literature. I also calculate the decay rate when the electric field wraps a compact…
