Computing Exact Self-Energies with Polynomial Expansion
M. Hyrkäs, D. Karlsson, R. van Leeuwen
We give details on how to calculate spectral functions and Green's functions for finite systems using the Chebyshev polynomial expansion method. We apply the method to a finite And…

Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equilibrium?
M. Hopjan, D. Karlsson, S. Ydman +2
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-bod…
