A team led by Prof. He Junfeng from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), together with domestic and international collaborators, discovered that the energy level of the van Hove singularity (VHS) in the novel Ti-based kagome metal CsTi3Bi5 can be tuned without lattice structural instability. Their work was published in Physical Review Letters on July 12 as the cover article.
