Interplane magnetic coupling effects in the multilattice compound Y_2Ba_4Cu_7O_{15}
G. Hildebrand, E. Arrigoni, J. Schmalian +1
We investigate the interplane magnetic coupling of the multilattice compound Y_2Ba_4Cu_7O_{15} by means of a bilayer Hubbard model with inequivalent planes. We evaluate the spin re…

Magnetic Properties of YBa_2Cu_3O_{7-δ} in a self-consistent approach: Comparison with Quantum-Monte-Carlo Simulations and Experiments
G. Hildebrand, E. Arrigoni, C. Gröber +1
We analyze single-particle electronic and two-particle magnetic properties of the Hubbard model in the underdoped and optimally-doped regime of \YBCO by means of a modified version…

Effects of Electronic Correlations on the Thermoelectric Power of the Cuprates
G. Hildebrand, T. J. Hagenaars, W. Hanke +2
We show that important anomalous features of the normal-state thermoelectric power S of high-Tc materials can be understood as being caused by doping dependent short-range antiferr…
