Self-Consistent Embedding of Density-Matrix Renormalization Group   Wavefunctions in a Density Functional Environment
  We present the first implementation of a density matrix renormalization group algorithm embedded in an environment described by density functional theory. The frozen density embedding scheme is used with a freeze-and-thaw strategy for a self-consistent polarization of the orbital-optimized wavefunction and the environmental densities with respect to each other.
