Anomalous Behavior of the Ni $^{1 +}$ moment in bi-infinite-layered La $_{3}$ Ni $_{2}$ O $_{5}$ F

Young-Joon Song, W. E. Pickett, K. -W. Lee

The discovery of superconductivity in hole-doped Ni $^{1 +}$ systems with ``infinite layer" NiO $_{2}$ square-lattices analogous to the Cu $^{2 +}$ CaCuO $_{2}$ cuprate has renewed conflicti…

Proposed ordering of textured spin singlets in a bulk infinite layer nickelate

Hyo-Sun Jin, W. E. Pickett, K. -W. Lee

The infinite-layer structure nickelate Ba $_{2}$ NiO $_{2}$ (AgSe) $_{2}$ (BNOAS) with $d^{8}$ Ni ions and a peculiar susceptibility $χ (T)$ is studied with correlated density functional methods…

Fluctuation-frustrated flat band instabilities in NdNiO2

Mi-Young Choi, W. E. Pickett, K. -W. Lee

The discovery that Nd $_{1 - x}$ Sr $_{x}$ NiO $_{2}$ , with the CaCuO $_{2}$ infinite-layer structure, superconducts up to 15 K around the hole-doping level $x$ =0.2 raises the crucial question o…

Charge and Orbital Orderings, and Frustration in Quasi-one-dimensional Ferrimagnetic Insulator $β$ -V $_{2}$ O(PO $_{4}$ )

Seo-Jin Kim, K. -W. Lee

Using ab initio calculations based on the correlated band theory, we have investigated the quasi-one-dimensional chain system $β$ -V $_{2}$ O(PO $_{4}$ ), showing both charge and spin order…

Noncentrosymmetric compensated half-metal hosting pure spin Weyl nodes, triple nodal points, nodal loops, and nexus fermions

Hyo-Sun Jin, Young-Joon Song, W. E. Pickett +1

Materials containing multiple topological characteristics become more exotic when combined with noncentrosymmetric crystal structures and unusual magnetic phases such as the compen…
