WebFeb 18, 2024 · Figure 1. Contour plot of the charge dynamical structure factor ln N (q, ω) obtained by the VMC method in the two different approaches for the one-dimensional Hubbard model with L = 14 and U / t = 8.The ED results are also shown for comparison. E 0 means the ground-state energy, i.e., E 0 = 〈 ψ ¯ H ψ ¯ 〉.To enhance the visibility … The Hubbard model is an approximate model used to describe the transition between conducting and insulating systems. It is particularly useful in solid-state physics. The model is named for John Hubbard. The Hubbard model states that each electron experiences competing forces: one pushes it to tunnel to neighboring atoms, while the other pushes it away fr…
