Claims

C1strongest claim

we provide compelling evidence for an intrinsic, interaction-driven quantum state, which we term the Nagaoka supermetal. This state is characterized by a sublinear temperature dependence in the DC resistivity, along with singular behaviors in the charge compressibility and zero-frequency spectral weight.

C2weakest assumption

That the singular transport and thermodynamic properties are fully captured by the higher-order Van Hove singularity in the derived effective low-energy model, without dominant contributions from other many-body effects, numerical artifacts, or unaccounted interaction terms.

C3one line summary

Particle doping of the triangular Hubbard model yields a Nagaoka supermetal whose anomalous transport and thermodynamic properties arise from a power-law divergent density of states at a higher-order Van Hove singularity.
