Low-order hybridization expansions fail in multi-orbital systems because the least correlated orbital suppresses correlation features across all orbitals through spurious couplings generated by the truncation.
Derives static effective Hamiltonians via cRPA and mRPA downfolding with double-counting corrections and compares performance on benzene ground state and bond dissociation curves.
i-DFT computes spectral and transmission properties of correlated quantum dots from Coulomb blockade to Kondo regimes, matching many-body results at reduced cost.
DFT+DMFT calculations on americium show partial 5f delocalization under pressure with valence mixing and link high-pressure phase stability to symmetry-lowering Peierls distortions.
Adapted TEBD in star geometry is the most efficient MPS method for real-time evolution of Anderson impurity models among the tested combinations.
