An observed correlation between the critical temperature of a superconducting transition in high-temperature superconductors and a proximity of their electronic structure to the topological Lifshitz transition needs to be verified on simple model materials. Here we show that such an object could be a Mo–Re alloy with an equal concentration of constituent elements. We present new evidence of the presence of two energy gaps in this material, obtained using point-contact spectroscopy, and argue that the studied Mo–Re alloy can be used for implementing new quantum effects associated with the phase difference of electron wave functions from the different bands.

Mo-Re合金中具有相同浓度成分的两波段超导性

需要在简单的模型材料上验证高温超导体中超导转变的临界温度与其电子结构与拓扑Lifshitz转变的接近程度之间所观察到的相关性。在这里，我们证明了这样的物体可能是具有相等浓度的组成元素的Mo-Re合金。我们提供了使用点接触光谱法获得的该材料中存在两个能隙的新证据，并认为所研究的Mo-Re合金可用于实现与电子波函数相差有关的新量子效应。不同的乐队。
