At zero o'clock on the 24th Beijing time, the academic journal Nature published the latest discovery made by Professor Wu Tao, a team of academicians Chen Xianhui from the University of Science and Technology of China, and others: using nuclear magnetic resonance spectroscopy under high pressure, a new type of charge order state induced by pressure was observed in the cage superconductor cesium vanadium antimony, and it was found that the charge order state and the superconducting state presented a competitive phase diagram similar to that of high-temperature superconductors under pressure. This achievement is another important discovery made by Academician Chen Xianhui's team after the report on the new electronic nematic phase in cage superconductors in Nature in February this year. In the study of unconventional superconductors, it is found that there is always a complex competition between superconducting states and competitive electronic states, and they can also be intertwined to further form novel superconducting states. It is one of the key problems in the field of superconductivity to explore the complex derivative phenomena and their physical mechanisms between superconducting states and competitive electronic states. In the previous study, the research team of the University of Science and Technology of China found that under pressure, there was an abnormal competition between the superconductive state and the charge density wave state in the cage superconductor, indicating that there might be an undiscovered competitive electronic order. In this work, Wu Tao and others carried out a nuclear magnetic resonance study on the Cs, V, Sb cage superconductors under pressure. The results showed that when the hydrostatic pressure was higher than about 6000 atmospheres, the superconductivity of the system was severely suppressed, and at the same time a new charge density wave state was derived, similar to the charge stripe order, a competitive electronic order found previously in high-temperature copper oxide superconductors. When the pressure is further increased to more than 20000 atmospheres, the new charge density wave state is completely suppressed, and the superconducting transition temperature also rises to the highest value. These results show that there is a strong competition between the new charge ordered state and the superconducting state, which is a new competitive electronic order. In addition, the research team also observed the charge fluctuation phenomenon caused by the electron correlation effect in cage superconductors and the possible unconventional superconductivity under pressure. Cage superconductor is a new type of superconducting material. Because of its special geometric structure and non local electronic correlation, it has shown many strange physical properties, and is considered to be a new type of quantum material with important scientific research value. This experiment revealed the novel electronic correlation effect and abundant derivative phenomena in cage superconductors, which provided a new opportunity to understand the complex interaction mechanism between superconducting states and competitive electronic states, and also provided a new direction for exploring novel superconducting states in cage superconductors. In addition, Wu Tao pointed out: "From the perspective of electron electron correlation interaction, although cage superconductors have weak correlation interaction, they have observed competitive electron sequences similar to high-temperature superconductors, which indicates that there may be a new electron electron correlation effect in cage superconductors, but the specific physical mechanism remains to be further explored."
