Query: Density matrix renormalization group boosted by Gutzwiller projected
  wave functions   We propose to boost the performance of the density matrix renormalization
group (DMRG) in two dimensions by using Gutzwiller projected states as the
initialization ansatz. When the Gutzwiller projected state is properly chosen,
the notorious "local minimum" issue in DMRG can be circumvented and the
precision of DMRG can be improved by orders of magnitude without extra
computational cost. Moreover, this method allows to quantify the closeness of
the initial Gutzwiller projected state and the final converged state after DMRG
sweeps, thereby sheds light on whether the Gutzwiller ansatz captures the
essential entanglement features of the actual ground state for a given
Hamiltonian. The Kitaev honeycomb model has been exploited to demonstrate and
benchmark this new method.
