Scan calculation of the density of states: real space cluster perturbation theory applied to inhomogeneous Hubbard model in one dimension

Kaito Matsuki, Chisa Hotta, Kenichi Asano

We present the spectral analysis of a one-dimensional Hubbard model with a parabolic potential, using a real-space cluster perturbation theory (rCPT) designed to study spatially in…
