Pairing without $γ$ -Pocket in the La $_{3}$ Ni $_{2}$ O $_{7}$ Thin Film

Zhi-Yan Shao, Chen Lu, Min Liu +4

The recent discovery of high-temperature superconductivity (HTSC) in the La $_{3}$ Ni $_{2}$ O $_{7}$ ultrathin film at ambient pressure has aroused great research interest. The $γ$ -pocket fo…

Unconventional magnetism in spin-orbit coupled systems

Jian-Keng Yuan, Zhiming Pan, Congjun Wu

``Unconventional magnetism" was proposed to describe the exotic states arising from Landau-Pomeranchuk instabilities in the spin channel nearly two decades ago. Its odd-partial-wav…

Strong-coupling study of the pairing mechanism in pressurized La $_{3}$ Ni $_{2}$ O $_{7}$

Jia-Heng Ji, Chen Lu, Zhi-Yan Shao +3

Recently, the bilayer perovskite nickelate La $_{3}$ Ni $_{2}$ O $_{7}$ has been reported to exhibit high-temperature superconductivity near $80$ K under a moderate pressure of about $14$ GPa.…

From $G_{2}$ to $S O (8)$ : Emergence and reminiscence of supersymmetry and triality

Zhi-Qiang Gao, Congjun Wu

We construct a (1+1)-dimension continuum model of 4-component fermions incorporating the exceptional Lie group symmetry $G_{2}$ . Four gapped and five gapless phases are identified vi…
