Ultrafast giant enhancement of second harmonic generation in a strongly correlated cobaltite
Yuchen Cui, Qiaomei Liu, Qiong Wu +15
In quantum materials, nonlinear optical responses are highly sensitive to electronic structure and many-body interactions. Probing and manipulating such nonlinear processes is a co…
Multimodal Terahertz Spectroscopy of the Pairing Symmetry and Normal-State Pseudogap in (La,Pr)NiO Films
Shuxiang Xu, Guangdi Zhou, Hao Wang +11
The discovery of ambient-pressure superconductivity in compressively strained (La,Pr)NiO thin films has intensified efforts to identify the pairing mechanism. However,…
Mn4Al11: A Half-Semimetal Candidate with Anomalous Electronic Behaviors
Shanshan Han, Rongsheng Li, Xingxing Jiang +5
Half-semimetals, characterized by their spin-polarized electronic states, hold significant promise for spintronic applications but remain scarce due to stringent electronic and mag…
Collapse of density wave and emergence of superconductivity in pressurized-LaNiO evidenced by ultrafast spectroscopy
Shuxiang Xu, Hao Wang, Mengwu Huo +7
Recent discoveries of superconductivity in Ruddlesden-Popper nickelates realize a rare category of superconductors. However, the use of high-pressure diamond anvil cells limits spe…
Field-induced spin continuum in twin-free NaCoSbO revealed by magneto-THz spectroscopy
Rongsheng Li, Liyu Shi, Yuchen Gu +9
The honeycomb magnet NaCoSbO recently emerged as a promising candidate for realizing Kitaev quantum spin liquid with relatively low levels of structural disorder. While…
