论文摘要
我们考虑了在空间紧凑的1+1维时段上的标量QED理论。通过考虑指向紧凑型尺寸的恒定电场，我们通过整合欧几里得部门的标量自由度来计算量子有效作用。在鞍点的近似中工作，我们在分析延续到实时时发现了两个新颖的分支/物理状态，并发现了一个新的结果，迄今未报告的新结果。讨论了我们的结果的含义。
We consider a theory of scalar QED on a spatially compact 1+1-dimensional spacetime. By considering a constant electric field pointing down the compact dimension, we compute the quantum effective action by integrating out the scalar degrees of freedom in the Euclidean sector. Working in the saddle-point approximation we uncover two novel branches/physical regimes upon analytically continuing back to real time and discover a new result, hitherto unreported in previous literature. Implications of our results are discussed.
