Density-Matrix Embedding Theory Study of the One-Dimensional Hubbard–Holstein Model

[Image: see text] We present a density-matrix embedding theory (DMET) study of the one-dimensional Hubbard–Holstein model, which is paradigmatic for the interplay of electron–electron and electron–phonon interactions. Analyzing the single-particle excitation gap, we find a direct Peierls insulator t...
