任意耦合下的热Schwinger对产生

Thermal Schwinger pair production at arbitrary coupling

Oliver Gould, Arttu Rajantie

摘要:

我们计算了弱外场中任意耦合下的热Schwinger对产生率。我们的计算是有效的,与所产生的带电粒子的许多性质无关,特别是它们的自旋以及它们是电的还是磁的。利用世界线方法,我们计算了弱外场中到首阶的速率的对数和虚光子交换中到各阶的速率的对数,从而使我们超越了关于首阶的微扰展开,得到了弱耦合的结果。

英文摘要:

We calculate the rate of thermal Schwinger pair production at arbitrary coupling in weak external fields. Our calculations are valid independently of many properties of the charged particles produced, in particular their spin and whether they are electric or magnetic. Using the worldline formalism, we calculate the logarithm of the rate to leading order in the weak external field and to all orders in virtual photon exchange, taking us beyond the perturbative expansion about the leading order, weak coupling result.
