Charge and spin Drude weight of the one-dimensional extended Hubbard model at quarter-filling
T. Shirakawa, E. Jeckelmann
We calculate the charge and spin Drude weight of the one-dimensional extended Hubbard model with on-site repulsion and nearest-neighbor repulsion at quarter filling using t…

Finite-size scaling of correlation functions in one-dimensional Anderson-Hubbard model
S. Nishimoto, T. Shirakawa
We study the one-dimensional Anderson-Hubbard model using the density-matrix renormalization group method. The influence of disorder on the Tomonaga-Luttinger liquid behavior is qu…
