Real-Time Out-of-Equilibrium Quantum Dynamics in Disordered Materials

Author(s): Luis M. Canonico, Stephan Roche, and Aron W. Cummings We report a linear-scaling numerical method for exploring nonequilibrium electron dynamics in systems of arbitrary complexity. Based on the Chebyshev expansion of the time evolution of the single-particle density matrix, the method gives access to nonperturbative excitation and relaxation phenomena … [Phys. Rev.
