Domains of time-dependent density-potential mappings
Markus Penz, Michael Ruggenthaler
The key element in time-dependent density functional theory is the one-to-one correspondence between the one-particle density and the external potential. In most approaches this ma…

On the existence of effective potentials in time-dependent density functional theory
M. Ruggenthaler, M. Penz, D. Bauer
We investigate the existence and properties of effective potentials in time-dependent density functional theory. We outline conditions for a general solution of the corresponding S…
