铜氧化合物高温超导体发现至今已过25年,但该材料的许多方面仍然充满着挑战。超导机理仅仅是其中的一个谜,在超导转变温度Tc之上,铜基超导体表现出了许多目前的凝聚态理论无法解释的、错综复杂的实验现象。最大的谜团之一是“赝能隙”的本源。“赝能隙”在铜基超导体的相图中占据很大一片
Copper oxide high-temperature superconductors have been found for over 25 years, but many aspects of the material are still challenging. The superconducting mechanism is just one of the mysteries. At a superconducting transition temperature Tc, copper-based superconductors exhibit many intricate experimental phenomena that can not be explained by the current condensed matter theory. One of the biggest mysteries is the origin of “pseudogap”. “Pseudo-energy gap ” in the copper-based superconductor phase diagram occupy a large piece
