Random-Phase-Approximation Description of Spinflip Modes in Polarized 3He

The transverse dynamical susceptibility of spin-polarized liquid helium, whose equation of state is described in a density functional formalism, is computed within the frame of an extended Random Phase Approximation. The dispersion relation of magnon peaks and dynamical structure factor are analyzed...

Descripción
Sumario:The transverse dynamical susceptibility of spin-polarized liquid helium, whose equation of state is described in a density functional formalism, is computed within the frame of an extended Random Phase Approximation. The dispersion relation of magnon peaks and dynamical structure factor are analyzed for polarizations up to 30%.
