    "abstract": "Response functions in nuclear matter at finite temperature are considered\nbeyond the usual Hartree-Fock (HF) plus Random Phase Approximation (RPA)\nscheme. The contributions due to the propagator for the dressed nucleons and\nthe corresponding vertex corrections are treated in a consistent way. For that\npurpose a semi-realistic Hamiltonian is developed with parameters adjusted to\nreproduce the nucleon self-energy as derived from realistic nucleon-nucleon\ninteractions. For a scalar residual interaction the resulting response\nfunctions are very close to the RPA response functions. However, the collective\nmodes, if present, get an additional width due to the coupling to multi-pair\nconfigurations. For isospin dependent residual interactions we find strong\nmodifications of isospin response functions due to multi-pair contributions in\nthe response function. Such a modification can lead to the disappearance of\ncollective spin or isospin modes in a correlated system and shall have an\neffect on the absorption rate of neutrinos in nuclear matter.",
