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…
Intrinsic exchange-correlation magnetic fields in exact current-density functional theory for degenerate systems
J. D. Ramsden, R. W. Godby
We calculate the exact Kohn-Sham (KS) scalar and vector potentials that reproduce, within current-density functional theory, the steady-state density and current density correspond…
Exact density-functional potentials for time-dependent quasiparticles
J. D. Ramsden, R. W. Godby
We calculate the exact Kohn-Sham potential that describes, within time-dependent density-functional theory, the propagation of an electron quasiparticle wavepacket of non-zero crys…
