Time-dependent exchange-correlation potential in lieu of self-energy
نویسندگان
چکیده
The equation of motion the Green's function a many-electron system is shown to be governed by multiplicative exchange-correlation potential, in contrast self-energy. Crucially, this potential simply Coulomb an hole and fulfills sum rule. formulation offers simple physical interpretation for propagation added electron or may provide route density-functional-like approximations calculating function.

Universal dynamical steps in the exact time-dependent exchange-correlation potential.
We show that the exact exchange-correlation potential of time-dependent density-functional theory displays dynamical step structures that have a spatially nonlocal and time nonlocal dependence on the density. Using one-dimensional two-electron model systems, we illustrate these steps for a range of nonequilibrium dynamical situations relevant for modeling of photochemical or physical processes:...
متن کاملTime-dependent analysis of carrier density and potential energy in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD)
Interaction and correlation effects in quantum dots play a fundamental role in defining both their equilibrium and transport properties. Numerical methods are commonly employed to study such systems. In this paper we investigate the numerical calculation of quantum transport of electrons in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD). The simulation is based on the imaginary time...

متن کاملCurrent-Dependent Exchange-Correlation Potential for Dynamical Linear Response Theory.
The frequency-dependent exchange-correlation potential, which appears in the usual Kohn-Sham formulation of a time-dependent linear response problem, is a strongly nonlocal functional of the density, so that a consistent local density approximation generally does not exist. This problem can be avoided by choosing the current-density as the basic variable in a generalized Kohn-Sham theory. This ...
متن کاملSeparation of the exchange-correlation potential into exchange plus correlation: An optimized effective potential approach.
Most approximate exchange-correlation functionals used within density-functional theory are constructed as the sum of two distinct contributions for exchange and correlation. Separating the exchange component from the entire functional is useful since, for exchange, exact relations exist under uniform density scaling and spin scaling. In the past, accurate exchange-correlation potentials have b...
