Luttinger Liquid Behavior in a Single-Layer Nickelate La1.4Sr0.6NiO4
Yinqi Hu, Yidian Li, Xian Du +19
The discovery of high-temperature superconductivity in bilayer and trilayer nickelates has spurred intense interest in the Ruddlesden-Popper nickelates; yet the fundamental propert…

Carrier duality from the convergence of Dirac fermions and high-order van Hove singularities
Meng Lyu, Kaiyi Zhai, Nikolai Peshcherenko +15
The convergence of highly mobile Dirac fermions and flat-band heavy electrons offers a paradigm for emergent quantum phenomena. However, experimental realization of such intriguing…

Orbital-selective Mottness Driven by Geometric Frustration of Interorbital Hybridization in Pr4Ni3O10
Yidian Li, Mingxin Zhang, Xian Du +22
The interplay among orbital-selective Mott physics, Hund's coupling, tunable structural motifs, and Kondo-like scattering establishes a compelling paradigm for understanding and en…
