We show that a new resonant magnetic excitation at incommensurate momenta, observed
recently by inelastic neutron scattering experiments on YBa 2 Cu 3 O 6.85 and YBa 2 Cu 3 O …

Linear response theory, commonly known as the random-phase approximation (RPA),
predicts a rich magnetic excitation spectrum for d-wave superconductors. Many of the …

We perform a comprehensive analysis of the dynamical magnetic susceptibility χ (q, ω) in
the slave-boson mean-field scheme of the bilayer tJ model. We use model parameters …

Based on the time-dependent Gutzwiller approximation for the extended Hubbard model, we
calculate the energy and momentum dependence of spin excitations for striped ground …

We report a neutron scattering study of the spin excitation spectrum in the superconducting
state of the slightly overdoped Bi 2 Sr 2 CaCu 2 O 8+ δ system (T c= 87 K). We focus on the …

We present inelastic neutron scattering data on highly overdoped Bi 2 Sr 2 Ca Cu 2 O 8+ δ
single crystals with superconducting transition temperature TC= 70 K and, for comparison, a …

We study the emergence of a magnetic resonance in the superconducting state of the
electron-doped cuprate superconductors. We show that the recently observed resonance …

High-resolution neutron inelastic scattering experiments in applied magnetic fields have
been performed on La 1.895 Sr 0.105 CuO 4 (LSCO). In zero field, the temperature …

Magnetic and bond-charge interactions can arise from the same microscopic interaction.
Motivated by this observation, we compute magnetic and bond-charge excitation spectra on …

Inelastic neutron scattering is a powerful technique that can measure magnetic correlations
in a large momentum and energy range. In strongly correlated electronic systems, where …
