我们研究了核库仑场和高强度双色激光场叠加中电子-正电子对的产生。我们的重点在于量子干涉效应，如果两个激光频率相当，则可能会出现量子干涉效应。我们表明，干扰体现在所创建粒子的角度分布中，这在核休息框架和实验室框架中进行了讨论。此外，我们证明了总的对生产速率可能会受到干扰的影响，并确定了两种激光模式之间的相对相位，从而优化了对生产良率。
We study the creation of electron-positron pairs in the superposition of a nuclear Coulomb field and a two-color laser field of high intensity. Our focus lies on quantum interference effects, which may arise if the two laser frequencies are commensurable. We show that the interference manifests in the angular distributions of the created particles, which are discussed in the nuclear rest frame and the laboratory frame. Additionally, we demonstrate that the total pair-production rates can be affected by interference and identify the relative phase between the two laser modes, which optimizes the pair-production yield.
