In the dilute limit of the 1D infinite-U Hubbard model the charge Drude weight admits a closed-form expression whose low-temperature expansion, after regularization of the singular contribution, yields linear-in-T resistivity.

Non-Fermi liquids from critical fluctuations are grouped into seven superuniversality classes by the topology of projective fixed-point bundles, which fix universal pairing strengths and set lower bounds on superconducting transition temperatures and symmetries.
Disorder in spin-stripe fluctuations maps onto a strange-metal quantum critical point and generates Fermi arcs when antiferromagnetic correlations are short.
