Collective excitations of infinite nuclear matter are investigated within the framework of the Landau theory of normal Fermi liquids. Numerical results are obtained using the existing sets of the Landau parameters of the quasi-particle interaction in nuclear matter. In the hydrodynamic regime all possible modes of the collective vibrations of the breathing, isospin, spin and spin-isospin type can be excited. In the collisionless regime the breathing mode is strongly damped, and only the longitudinal isospin, spin, and spin-isospin modes may propagate, the velocity of propagation being slightly greater than the quasi-particle velocity at the Fermi surface.read more

Isospin and density waves in asymmetric nuclear matter
TL;DR: In this paper, the excitation of small density oscillations and isospin oscillations (isospin sound) in cold asymmetric nuclear matter was investigated under the Landau theory of normal Fermi liquids.

Isospin waves in asymmetric nuclear matter
TL;DR: In this paper, the transverse isospin wave in asymmetric (N ≠ Z ) nuclear matter was investigated and the isobaric analogue state and the giant Gamow-Teller resonance of nuclear matter were identified.

Coupling of isospin oscillations to density oscillations in asymmetric nuclear matter
TL;DR: In this article, the excitation of small isospin oscillations in cold asymmetric nuclear matter was investigated within the framework of the Landau theory, and the undamped mode of these oscillations was shown to contain an admixture of density oscillations.

Correlation Energy of an Electron Gas at High Density
TL;DR: In this article, the correlation energy of an electron gas at high density is evaluated up to terms of orders of magnitude (n, r, s) and log(r, s), where r is the number of electrons in the gas.

Correlation energy of an electron gas at high density: plasma oscillations
TL;DR: In this article, the contribution of zero-point plasma oscillations to the correlation energy of an electron gas at high density is considered, using the exact high-density theory of GellMann and Brueckner and of Sawada.
