Density matrix renormalizationgroup calculations quantitatively reproduce and help understand the observed commensurate and incommensurate excitations.
2
With the density matrix renormalizationgroup we also compute near-exact vertical excitation energies at the equilibrium geometry.
3
The density matrix renormalizationgroup is a method that is useful for describing molecules that have strongly correlated electrons.
4
We describe in detail our high-performance density matrix renormalizationgroup (DMRG) algorithm for solving the electronic Schrodinger equation.
5
We present a complete, group-theoretic classification of such transitions into seven distinct cases (including cases with nematic order) and analyze fluctuations by the renormalizationgroup.
