Magnetic properties of the 2D t-t'-Hubbard model
U. Trapper, H. Fehske, D. Ihle
The two-dimensional (2D) t-t'-Hubbard model is studied within the slave-boson (SB) theory. At half-filling, a paramagnetic to antiferromagnetic phase transition of first order at a…
Theory of magnetic short-range order for itinerant electron systems
U. Trapper, D. Ihle, H. Fehske
On the basis of the one--band t-t'-Hubbard model a self-consistent renormalization theory of magnetic short--range order (SRO) in the paramagnetic phase is presented combining the…
Theory of short-range magnetic order for the t-J model
C. Schindelin, U. Trapper, H. Fehske +1
We present a self-consistent theory of magnetic short-range order based on a spin-rotation-invariant slave-boson representation of the 2D t-J model. In the functional-integral sche…
Theory of Magnetic Short--Range Order for High-T_c Superconductors
U. Trapper, D. Ihle, H. Fehske
A theory of magnetic short--range order for high-- cuprates is presented on the basis of the one--band ----Hubbard model combining the four--field slave--boson…
Spin susceptibility and magnetic short-range order in the Hubbard model
U. Trapper, D. Ihle, H. Fehske
The uniform static spin susceptibility in the paraphase of the one-band Hubbard model is calculated within a theory of magnetic short--range order (SRO) which extends the four-fiel…
