Conserving approximation for the three-band Hubbard model: flat quasiparticle dispersion
R. Putz, R. Preuss, A. Muramatsu +1
It is shown that the low-energy single-particle excitation-spectrum of the three-band Hubbard model at hole-dopings away from half-filling agrees remarkably well with Quantum Monte…

Spectral properties of the one-dimensional Hubbard model
R. Preuss, A. Muramatsu, W. von der Linden +2
The spectral properties of the 1-D Hubbard model are obtained from quantum Monte Carlo simulations using the maximum entropy method. The one-particle excitations are characterized…
