强背景下的费米子介子

The Fermionic Propagator in an Intense Background

Martin Lavelle, David McMullan

摘要:

给出了激光背景下费米子传播子的新结果。我们表明,所有订单的电子传播子可以写在一个紧凑的和有吸引力的形式作为一个矩阵波函数重整化和矩阵值的质量移动的边带极点的总和。如果我们坚持质量及其平方只在e^2阶时才发生修正,那么最后一个结果在费米理论中是必不可少的。我们的结果进行了微扰验证。

英文摘要:

New results for the fermion propagator in a laser background are presented. We show that the all orders electron propagator can be written in a compact and appealing form as a sum of sideband poles with a matrix wave function renormalisation and a matrix valued mass shift. This last result is essential in the fermionic theory if we are to maintain that both the mass and its square pick up a correction only at order e^2. A perturbative verification of our results is carried out.
