Local density approximations from finite systems
Mike Entwistle, Matthew Hodgson, Jack Wetherell +3
The local density approximation (LDA) constructed through quantum Monte Carlo calculations of the homogeneous electron gas (HEG) is the most common approximation to the exchange-co…
Origin of static and dynamic steps in exact Kohn-Sham potentials
M. J. P. Hodgson, J. D. Ramsden, R. W. Godby
Knowledge of exact properties of the exchange-correlation (xc) functional is important for improving the approximations made within density functional theory. Features such as step…
Electron localisation in static and time-dependent one-dimensional model systems
T. R. Durrant, M. J. P. Hodgson, J. D. Ramsden +1
Electron localization is the tendency of an electron in a many-body system to exclude other electrons from its vicinity. Using a new natural measure of localization based on the ex…
The role of electron localization in density functionals
M. J. P. Hodgson, J. D. Ramsden, T. R. Durrant +1
We introduce a new functional for simulating ground-state and time-dependent electronic systems within density-functional theory. The functional combines an expression for the exac…
Adiabatic and local approximations for the Kohn-Sham potential in time-dependent Hubbard chains
L. Mancini, J. D. Ramsden, M. J. P. Hodgson +1
We obtain the exact Kohn-Sham potentials of time-dependent density-functional theory for 1D Hubbard chains, driven by a d.c.\ external field, using the time-depen…
Exact time-dependent density-functional potentials for strongly correlated tunneling electrons
Matthew J. P. Hodgson, James D. Ramsden, Jacob B. J. Chapman +2
By propagating the many-body Schrödinger equation, we determine the exact time-dependent Kohn-Sham potential for a system of strongly correlated electrons which undergo field-induc…
