TLDR
In this article, the equivalence of the two methods is discussed in the context of RPA collective modes in nuclear matter, and two different approaches to the theory, one due to Landau and the other to van Kampen, are discussed.About:

Collective modes in hot and dense nuclear matter.
TL;DR: It is observed that the effective mass of scalar and vector mesons raises only slightly with temperature for [ital T][lt]180 MeV while the effective nucleon mass decreases.

Collective modes in relativistic asymmetric nuclear matter
TL;DR: In this paper, isospin and density waves in asymmetric nuclear matter (ANM) were studied in the framework of relativistic mean-field hadron models, and the condition for the existence of each type of mode was referred.
Journal ArticleDOI
Collective modes in relativistic nuclear matter: Classical approach.
TL;DR: A classical relativistic approach based in the Vlasov equation is applied to the study of infinite nuclear matter and it is seen that the scalar field only couples to the low-energy excitations at high densities and for wavelengths not too long.

Time dependent Hartree-Fock approach to the bosonic excitations of the Nambu-Jona-Lasinio model in the continuum
J. da Providencia,C. A. de Sousa +1 more
TL;DR: In this article, the original NJL model is investigated in the framework of a variational approximation for the generators of the mesonic excitations, and all the meson modes are described in a unified way as excitations of q q pairs.

Meson resonances in a generalized Nambu and Jona-Lasinio model
TL;DR: In this paper, the authors analyse an extended Nambu and Jona-Lasinio model in the context of the conventional RPA treatment and of a variational approximation which corresponds to the discretization of the continuum, allowing to describe mesonic resonances that are treated as composite q\(bar q) systems.

The Theory of a Fermi Liquid
TL;DR: In this article, a theory of the Fermi liquid is constructed, based on the representation of the perturbation theory as a functional of the distribution function, and the effective mass of the excitation is found, along with the compressibility and the magnetic susceptibility.

On the theory of stationary waves in plasmas
TL;DR: In this paper, it is shown that the dispersion equation can be overcome by a proper treatment, which leads to a complete set of stationary solutions, which are much more numerous than the usual plasma oscillations.

Solution of the Vlasov equation for collective modes in nuclei
TL;DR: In this paper, a semiclassical theory of giant resonances based on the Vlasov equation is developed for the bound motion of particles in a central potential with an external time-dependent multipole field.

Van Kampen waves in extended fermi systems and the Random Phase Approximation
TL;DR: In this article, an orthogonal and complete set of solutions to the Random Phase Approximation (RPA) to the linearized Vlasov equation for an infinite, homogeneous many-fermion system was constructed.
