Random Hamiltonian in thermal equilibrium
- 1. Department of Mathematics, Imperial College London, London SW7 2AZ (United Kingdom)
Description
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.
