The Landau parameters in relativistic nonlinear models Original Research Article

The Landau parameters have been calculated in relativistic nonlinear models, on the one hand from the second derivative of the total energy density with respect to the quasinucleon distribution, on the other from the longitudinal dielectric function in relativistic RPA with and without the Pauli blocking terms in the polarization operators. The links between the Landau parameters and the collective modes obtained in the space-like region have been discussed.
