Unconventional Superconductivity in $\mathrm{L}{\mathrm{a}}_3\mathrm{N}{\mathrm{i}}_2{\mathrm{O}}_7$ from the Perspective of Symmetry

Guan-Hao Feng, Jun Quan, Yusheng Hou

The recently discovered superconductor $\mathrm{L}{\mathrm{a}}_3\mathrm{N}{\mathrm{i}}_2{\mathrm{O}}_7$ has attracted significant attention due to its remarkably high transition temperature ($T_c$) under high press…
