Underestimated Schwinger threshold in dimension-reduced approach
We perform a large scale of quantum field theoretical simulations in 1+1 spacetime, to examine the Schwinger threshold in a spatially finite-extended electric field. We get a smaller field threshold compared to that introduced by the Schwinger’s formula as well as the worldline instantons. We also c...
