Density matrix embedding theory
text:
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 modeled by a post-Hartree–Fock solver. This method has shown high-quality results in 1D- and 2D- Hubbard models,
and in chemical model systems incorporating the fully interacting electronic Hamiltonian, including long-range intera
