The spectral density of the spin susceptibility exhibits incommensurate peaks similar to those observed by neutron scattering in La2-xSrxCuO4. No spin-density-wave instability is found down to the lowest temperatures T (greater than or similar to 40 K) and up to the largest n (less than or similar to 0.85) and couplings U/t (less than or similar to 5) treated in this paper. For the same parameter space we calculate the eigenvalues of the superconducting eigen-solutions with d-wave and extended s-waves symmetry. These eigenvalues increase as T is decreased and n is increased, however, they are always far below unity which means that one is far from a superconducting transition. The calculated normal-state quantities are in qualitative agreement with the measured quantities of the cuprates, for example, the electrical resistivity is nearly a linear function of T like that of YBa2Cu3O7.","lang":"eng"}],"department":[{"_id":"10028"},{"_id":"29105470"}],"date_submitted":"2011-09-16T09:19:30Z","status":"public","author":[{"autoren_ansetzung":["Dahm, Thomas","Dahm","Thomas Dahm","Dahm, T","Dahm, T.","T Dahm","T.
