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…
Ultrafast Orbital-Selective Photodoping Melts Charge Order in Overdoped Bi-based Cuprates
Xinyi Jiang, Qizhi Li, Qingzheng Qiu +10
High-temperature superconductivity in cuprates remains one of the enduring puzzles of condensed matter physics, with charge order (CO) playing a central yet elusive role, particula…
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…
Photo-induced Dynamics and Momentum Distribution of Chiral Charge Density Waves in 1T-TiSe
Qingzheng Qiu, Sae Hwan Chun, Jaeku Park +14
Exploring the photoinduced dynamics of chiral states offers promising avenues for advanced control of condensed matter systems. Photoinduced or photoenhanced chirality in 1T-TiSe$_…
Selective excitation of collective modes in multiband superconductor MgB2
Jiayu Yuan, Liyu Shi, Tiequan Xu +7
