SUMMARY
This discussion focuses on determining the number of particles per site in the context of Fermionic Density Matrix Renormalization Group (DMRG) applied to the Hubbard model. The traditional formalism of DMRG is utilized, specifically referencing the Hamiltonian H = -t ∑i ∑σci,σ ci+1,σ + U∑ini,σni,σ. The paper cited, https://arxiv.org/abs/1108.6057, demonstrates the choice of 128 sites for R-DMFT, emphasizing the importance of finite-size effects and finite-size scaling in the analysis.
