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…

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…

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…
