Tunable Superconductivity in 1313-La $_{3}$ Ni $_{2}$ O $_{7}$ : Suppressed under Compression and Possible $s^{\pm}$ Pairing under Tension

Yang Zhang, Ling-Fang Lin, Adriana Moreo +2

Motivated by recent progress in the 1313-La $_{3}$ Ni $_{2}$ O $_{7}$ nickelate thin films (Nie et al., Nature {\bf 652}, 628 (2026)), we systematically investigate the effects of both compre…

Intertwined charge, spin, and orbital degrees of freedom under electronic correlations in the one-dimensional Fe $^{3 +}$ chalcogenide chain

Yang Zhang, Pontus Laurell, Gonzalo Alvarez +4

Motivated by recent developments in the study of quasi-one-dimensional iron systems with Fe $^{2 +}$ , we comprehensively study the Fe $^{3 +}$ chalcogenide chain system. Based on first…

Interlayer Pairing in Bilayer Nickelates

Thomas A. Maier, Peter Doak, Ling-Fang Lin +3

The discovery of $T_{c} \sim 80$ ~K superconductivity in pressurized La $_{3}$ Ni $_{2}$ O $_{7}$ has launched a new platform to study high-temperature superconductivity. Using non-perturbative d…

Magnon damping and mode softening in quantum double-exchange ferromagnets

A. Moreo, E. Dagotto, G. Alvarez +3

We present a comprehensive analysis of the magnetic excitations and electronic properties of fully quantum double-exchange ferromagnets, i.e., systems where ferromagnetic ordering…

General trends of electronic structures, superconducting pairing, and magnetic correlations in the Ruddlesden-Popper nickelate $m$ -layered superconductors La $_{m + 1}$ Ni $_{m}$ O $_{3 m + 1}$

Yang Zhang, Ling-Fang Lin, Adriana Moreo +3

We report a comprehensive theoretical analysis of the Ruddlesden-Popper layered nickelates La $_{m + 1}$ Ni $_{m}$ O $_{3 m + 1}$ ( $m = 1$ to 6) under pressure. Our results suggest that, while…

Novel phenomena in transition-metal oxide thin films and heterostructures with strong correlations and spin-orbit coupling

Satoshi Okamoto, Narayan Mohanta, Ho Nyung Lee +2

Transition-metal oxides have been a central subject of condensed matter physics for decades. In addition to novel electronic states driven by the influence of strong correlation, r…
