Abstract
We studied the dynamical spin susceptibility within the Hubbard model for hole-doped cuprates using cluster perturbation-based methods. Together with the one-electron spectral function, the two-particle response for 3 × 3 and 4 × 4 clusters are calculated and compared to each other. The results obtained are in qualitative agreement with the resonant inelastic neutron scattering and quantum Monte Carlo data.
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
