Magnetoresistance in the strange metallic phase of the Hubbard model

The normal state of high-Tc cuprate superconductors exhibit a variety of unusual transport properties incompatible with standard Fermi liquid theory, such as T-linear resistivity exceeding the Mott-Ioffe-Regel (MIR) limit and strongly doping- and temperature-dependent electrical and thermal Hall coefficients. However, certain conventional results appear unexpectedly intact. For instance, a correspondence between the electrical Hall coefficient and Fermi surface topology has been noted, and the Wiedermann-Franz law is approached at low temperatures. Such inconsistencies invite further investigation into which aspects of Fermi liquid theory and semiclassical transport theory retain their validity in strongly correlated cuprate materials. In this work, we address this question by using determinant quantum Monte Carlo (DQMC) to study the single-band Hubbard model, which has been shown to capture certain essential features of cuprates, and calculate the temperature and magnetic field dependence of magnetoresistance. In particular, we address whether the semiclassical Kohler's rule for magnetoresistance is violated, providing additional insight into the anomalous nature of transport in cuprates.
