Acoustic phonons in piezoelectric materials strongly couple to electrons through a macroscopic electric field. We show that this coupling leads to a momentum-dependent divergence of the Fan-Migdal electron linewidth. We then develop a self-consistent theory for calculating electron linewidths, which not only removes this piezoelectric divergence but also considerably modifies the linewidth in nonpiezoelectric, polar materials. Our predictions await immediate experimental confirmation, and this self-consistent method should be broadly used in interpreting various experiments on the electronic properties of real materials.

电子声子散射的自洽电子寿命

压电材料中的声声子通过宏观电场与电子强烈耦合。我们证明这种耦合会导致 Fan-Migdal 电子线宽的动量相关发散。然后，我们开发了一种用于计算电子线宽的自洽理论，该理论不仅消除了这种压电发散，而且还大大改变了非压电极性材料的线宽。我们的预测有待立即的实验证实，这种自洽的方法应该广泛用于解释真实材料电子特性的各种实验。
