Exact density functional theory with the density matrix renormalization group
density functional theory density matrix renormalization group electronic structure models

2011/8/17
Abstract: Combining density functional theory with controlled numerical methods for strongly correlated systems could greatly extend the range of both. We use the density matrix renormalization group ...
Exploring Interatomic Coulombic Decay by Free Electron Lasers
Free Electron Lasers Interatomic Coulombic
font style='font-size:12px;'>
2011/8/29
To exploit the high intensity of laser radiation, we propose to select frequencies at which singlephoton absorption is of too low energy and two or more photons are needed to produce states of an atom...
