摘要

我们用严谨的数学方法证明，电子-声子相互作用增强了多电子系统低温相中电荷密度波的稳定性。我们的证明方法是将皮拉戈夫-西奈理论恰当地应用于电子-声子系统。将我们的发现与现有结果相结合，我们获得了有关半填充电子-声子系统低温相图的严格信息。

Stability of Charge Density Waves in Electron–Phonon Systems

With mathematical rigor, we demonstrate that electron–phonon interactions enhance the stability of charge density waves in low-temperature phases of many-electron systems. Our proof method involves an appropriate application of the Pirogov–Sinai theory to electron–phonon systems. Combining our findings with existing results, we obtain rigorous information regarding the low-temperature phase diagram for half-filled electron–phonon systems.
