متن کاملTime-dependent density functional theory for quantum transport.
Based on our earlier works [X. Zheng et al., Phys. Rev. B 75, 195127 (2007); J. S. Jin et al., J. Chem. Phys. 128, 234703 (2008)], we propose a rigorous and numerically convenient approach to simulate time-dependent quantum transport from first-principles. The proposed approach combines time-dependent density functional theory with quantum dissipation theory, and results in a useful tool for st...
متن کاملTime-dependent density functional theory.
Time-dependent density functional theory (TDDFT) can be viewed as an exact reformulation of time-dependent quantum mechanics, where the fundamental variable is no longer the many-body wave function but the density. This time-dependent density is determined by solving an auxiliary set of noninteracting Schrodinger equations, the Kohn-Sham equations. The nontrivial part of the many-body interacti...

متن کاملTime Dependent Density Functional Theory in Quantum Liquids
The density functional (DF) approach is a well established theory for investigating important ground state properties (energies and density profiles) of quantum many body systems. In the last decades it has been systematically applied (mainly in the so called local density approximation) to a large variety of electronic systems. Applications to strongly interacting quantum systems (helium) has ...
