| Abstract: | A framework for the investigation of disordered quantum systems in thermal equilibrium is proposed. The approach is based on a dynamical model—which consists of a combination of a double-bracket gradient flow and a uniform Brownian fluctuation—that 'equilibrates' the Hamiltonian into a canonical distribution. The resulting equilibrium state is used to calculate quenched and annealed averages of quantum observables. |
