Density matrix embedding theory : ウィキペディア英語版 | Density matrix embedding theory
The density matrix embedding theory (DMET) is a numerical technique to solve strongly correlated electronic structure problems. By mapping the system to a fragment plus its entangled quantum bath, the local electron correlation effects on the fragment can be accurately modelled by a post-Hartree–Fock solver. This method has shown high-quality results in 1D- and 2D- Hubbard models.〔(Princeton.edu ) retrieved on 2015-09-07. 〕 ==References==
