Emergent Vibronic Spectral Hierarchy in a Kagome Flat-Band Insulator
Jun Shu, Jun Shen, Yanmin Zhang +17
Electron-phonon coupling is usually understood in terms of electronic quasiparticles interacting with dispersive lattice vibrations. Much less is known about the complementary limi…
Unconventional Pressure Evolution of Spin-Density-Wave State in LaNiO
Xiaoxiang Zhou, Shiyu Xie, Liangxin Qiao +13
The discovery of pressure-induced high temperature superconductivity in the bilayer nickelate LaNiO has raised the question of how its spin-density-wave (SDW) sta…
Fractional phase slips across the charge-density-wave domain walls in 1-T TiSe2
Haotian Zhang, Zihao Song, Zhongchen Xu +9
The microscopic origin of the charge density wave (CDW) in 1\textit{T}-TiSe remains controversial, with competing scenarios based on phonon-driven lattice instability and elect…
Anisotropic Electronic Correlations in the Spin Density Wave State of LaNiO
Ge He, Jun Shen, Shiyu Xie +21
The bilayer nickelate superconductor LaNiO undergoes a density wave transition near 150 K that has attracted intensive scrutiny, yet its microscopic origin remains elus…
Contrasting Momentum-Selective Spin-Density-Wave Gaps in Bilayer and Trilayer Nickelates
Jun Shu, Jun Shen, Xiaoxiang Zhou +12
Resolving where the density-wave gap opens in momentum space is essential for identifying the microscopic origin of the instability in layered nickelates. Using polarization-resolv…
