摘要：
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 con-centration of constituent elements. We present new evidence of the presence of two energy gaps in this material, ob-tained 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. © V.
