Magnetic and Charge Correlations of the 2-dimensional Hubbard model
Raymond Frésard, Walter Zimmermann
Using a spin-rotation invariant six-slave boson representation, we study the square lattice Hubbard model with nearest-neighbor hopping and next-nearest neighbor hopping .…

Spin and Charge Structure Factor of the 2-d Hubbard Model
Walter Zimmermann, Raymond Fresard, Peter Woelfle
The spin and charge structure factors are calculated for the Hubbard model on the square lattice near half-filling using a spin-rotation invariant six-slave boson representation. T…
