Two $T$-linear scattering rate regimes in the triangular lattice Hubbard model
Abstract
In recent years, the -linear scattering rate found at low temperatures, defining the strange metal phase of cuprates, has been a subject of interest. Since a wide range of materials have a scattering rate that obeys the equation , the idea of a universal Planckian limit on the scattering rate has been proposed. However, there is no consensus on proposed theories yet. In this work, we present our results for the -linear scattering rate in the triangular lattice Hubbard model obtained using the dynamical cluster approximation. We find two regions with -linear scattering rate in the -- phase diagram: one emerges from the pseudogap to correlated Fermi liquid phase transition at low doping, whereas the other is solely caused by large interaction strength at large doping.
