Finite energy spectral function of an anisotropic 2D system of coupled Hubbard chains

P. Ribeiro, P. D. Sacramento, K. Penc

We study the crossover from the one-dimensional to the two-dimensional Hubbard model in the photoemission spectra of weakly coupled chains. The chains with on-site repulsion are tr…
