The Superconducting Critical Temperature

论文摘要
两个原理决定了超导转换的临界温度:(1)〜对耦合的内在强度和多体环境对该耦合效率的影响。大多数讨论仅考虑了第一个,但我们认为,非常规超导体的性质通过与正常和超导状态有关的动态对称性更频繁地控制第二个。区分这些效果对于将通往最高温度超导体的路径绘制至关重要。
Two principles govern the critical temperature for superconducting transitions: (1)~intrinsic strength of the pair coupling and (2)~effect of the many-body environment on the efficiency of that coupling. Most discussions take into account only the first but we argue that the properties of unconventional superconductors are governed more often by the second, through dynamical symmetry relating normal and superconducting states. Differentiating these effects is essential to charting a path to the highest-temperature superconductors.
