Abstract

For the spin-1/2 Fermi-Hubbard model, we derive the kinetic equation valid for weak interactions by using a time-dependent perturbation expansion up to second order. In recent theoretical and numerical studies, the kinetic equation has merely been stated without further details. In this contribution, we provide the required background material.
