论文摘要
众所周知，准二维超导体遭受了配对波动的影响，这些波动会显着降低超导温度，甚至完全抑制任何相干行为。在这里，我们证明了与强大的对凝结凝结的耦合极大地改变了情况。在这种情况下，准二维系统可以是一个高温超导体，该高温超导体由靠近Lifshitz过渡的距离，在该过渡中，费米水平接近单粒子光谱的下边缘。
It is well-known that quasi-one-dimensional superconductors suffer from the pairing fluctuations that significantly reduce the superconducting temperature or even completely suppress any coherent behavior. Here we demonstrate that a coupling to a robust pair condensate changes the situation dramatically. In this case the quasi-one-dimensional system can be a high temperature superconductor governed by the proximity to the Lifshitz transition at which the Fermi level approaches the lower edge of the single-particle spectrum.
