Spectral moment sum rules for the retarded Green's function and self-energy of the inhomogeneous Bose-Hubbard model in equilibrium and nonequilibrium
J. K. Freericks, V. Turkowski, H. R. Krishnamurthy +1
We derive expressions for the zeroth and the first three spectral moment sum rules for the retarded Green's function and for the zeroth and the first spectral moment sum rules for…
Transition metal impurity-induced generation of plasmonic collective modes in small gold clusters
N. Nayyar, A. Kabir, V. Turkowski +1
We study the optical properties of small gold chains doped with different transition metal (TM) atoms (Ni,Rh,Fe) by using the time-dependent density-functional theory (TDDFT) appro…
Time-dependent density-functional approach for exciton binding energies
V. Turkowski, C. A. Ullrich
Optical processes in insulators and semiconductors, including excitonic effects, can be described in principle exactly using time-dependent density-functional theory (TDDFT). Start…
Time-dependent density-functional theory for ultrafast interband excitations
V. Turkowski, C. A. Ullrich
We formulate a time-dependent density functional theory (TDDFT) in terms of the density matrix to study ultrafast phenomena in semiconductor structures. A system of equations for t…
Phase diagram in 2D Fröhlich model of metal at arbitrary carrier density: pseudogap versus doping
V. M. Loktev, S. G. Sharapov, V. M. Turkowski
It is shown that in 2D system of the fermions with simplest indirect boson-induced attraction (through the Einstein phonon exchange as an example) along with the normal and superco…
