Hubbard-to-Heisenberg crossover (and efficient computation) of Drude weights at low temperatures
We illustrate how finite-temperature charge and thermal Drude weights of one-dimensional systems can be obtained from the relaxation of initial states featuring global (left–right) gradients in the chemical potential or temperature. The approach is tested for spinless interacting fermions as well as...
