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.

DQMC simulations of the doped Hubbard model find that Hall conductivity, unlike robust T-linear resistivity, is sensitive to asymmetry and Fermi surface details and reveals a crossover to quantum-coherent transport.

Transport and Temperature 1: Exact spectrum and resistivity for the one-dimensional infinite-$U$ Hubbard model
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.

Hall conductivity reveals the nature of quantum coherence in strongly correlated metals
DQMC simulations of the doped Hubbard model find that Hall conductivity, unlike robust T-linear resistivity, is sensitive to asymmetry and Fermi surface details and reveals a crossover to quantum-coherent transport.
