Abstract
We use the time-dependent Gutzwiller approximation for the Hubbard model in order to compute random-phase approximation-like (RPA) fluctuations on top of the Gutzwiller approximation (GA). No restrictions are imposed on the charge and spin configurations which makes the method suitable for the calculation of linear excitations around symmetry-broken solutions. Within this formalism, we investigate static and dynamical properties in the charge and spin channel of stripe textures in cuprates.File in questo prodotto:
