Excitonic effects in solids described by time-dependent density functional theory
Lucia Reining, Valerio Olevano, Angel Rubio +1
Starting from the many-body Bethe-Salpeter equation we derive an exchange-correlation kernel that reproduces excitonic effects in bulk materials within time-dependent dens…
Surface versus crystal-termination effects in the optical properties of surfaces
Rodolfo Del Sole, Giovanni Onida
We prove, by realistic microscopic calculations within the sp^3s^* Tight Binding method for GaAs (110) and (100), that the surface optical properties are not influenced by long-ran…
Study of a Nonlocal Density scheme for electronic--structure calculations
Maurizia Palummo, Giovanni Onida, Rodolfo Del Sole
An exchange-correlation energy functional beyond the local density approximation, based on the exchange-correlation kernel of the homogeneous electron gas and originally introduced…
Elimination of unoccupied state summations in ab-initio self-energy calculations for large supercells
Lucia Reining, Giovanni Onida, R. W. Godby
We present a new method for the computation of self-energy corrections in large supercells. It eliminates the explicit summation over unoccupied states, and uses an iterative schem…
Analytical expressions for the local-field factor G(q) and the exchange-correlation kernel K_{xc}(r) of the homogeneous electron gas
Massimiliano Corradini, Rodolfo Del Sole, Giovanni Onida +1
We present an analytical expression for the local field factor G(q) of the homogeneous electron gas which reproduces recently published Quantum Monte--Carlo data by S. Moroni, D.M.…
Ab initio calculation of excitonic effects in the optical spectra of semiconductors
Stefan Albrecht, Lucia Reining, Rodolfo Del Sole +1
An ab initio approach to the calculation of excitonic effects in the optical absorption spectra of semiconductors and insulators is formulated. It starts from a quasiparticle bands…
