Magnetic susceptibility of the two-dimensional two-sublattice Hubbard model calculated in the static-fluctuation approximation

摘要

The transverse dynamic susceptibility of the 2D two-sublattice Hubbard model is calculated in the static-fluctuation approximation. The static magnetic susceptibility is studied as a function of various parameters of the system. The results for the special case of the one-dimensional Hubbard model are compared to the exact solution. (c) 2005 Pleiades Publishing, Inc.
