Time-dependent density-functional theory for electronic excitations in materials: basics and perspectives
C. A. Ullrich, V. Turkowski
Time-dependent density-functional theory (TDDFT) is widely used to describe electronic excitations in complex finite systems with large numbers of atoms, such as biomolecules and n…

Spin fluctuations and the "strange metal" behavior of a weakly doped antiferromagnet
V. M. Loktev, V. Turkowski
We analyze the spectral properties of a phenomenological model for a weakly doped two-dimensional antiferromagnet, in which the carriers move within one of the two sublattices wher…

Nonequilibrium sum rules for the retarded self-energy of strongly correlated electrons
V. Turkowski, J. K. Freericks
We derive the first two moment sum rules of the conduction electron retarded self-energy for both the Falicov-Kimball model and the Hubbard model coupled to an external spatially u…
