Real-time electron dynamics with exact-exchange time-dependent density-functional theory.

چکیده
The exact exchange potential in time-dependent density-functional theory is defined as an orbital functional through the time-dependent optimized effective potential (TDOEP) method. We numerically solve the TDOEP integral equation for the real-time nonlinear intersubband electron dynamics in a semiconductor quantum well with two occupied subbands. It is found that memory effects become significant in the vicinity of intersubband resonances.

We obtain an exact solution of the time-dependent Schrödinger equation for a two-electron system confined to a plane by an isotropic parabolic potential whose curvature is periodically modulated in time. From this solution we compute the exact time-dependent exchange correlation potential vxc which enters the Kohn-Sham equation of time-dependent density functional theory. Our exact result provi...
متن کاملAdiabatic approximation in nonperturbative time-dependent density-functional theory.
We construct the exact exchange-correlation potential of time-dependent density-functional theory and the approximation to it that is adiabatic but exact otherwise. For the strong-field double ionization of the Helium atom these two potentials are virtually identical. Thus, memory effects play a negligible role in this paradigm process of nonlinear, nonperturbative electron dynamics. We identif...
متن کاملNumerical aspects of real-space approaches to strong-field electron dynamics
Numerical methods for calculating strong-field, nonperturbative electron dynamics are investigated. Two different quantum-mechanical approaches are discussed: the time-dependent Schrödinger equation and time-dependent density functional theory. We show that when solving the time-dependent Schrödinger equation, small errors in the initial ground-state wave function can be magnified considerably ...

We report a first-principles computational method to describe many-electron dynamics in crystalline solids. The method is based on the time-dependent density functional theory, solving the time-dependent Kohn-Sham equation in real time and real space. The calculation is efficiently parallelized by distributing computations of different k-points among processors. To illustrate the usefulness of ...
متن کاملUniversal 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:...
