Charge and spin response of the spin-polarized electron gas
- Department of Physics and Astronomy, University of Tennessee, Knoxville, Tennessee 37996 (United States)
The charge and spin response of a spin-polarized electron gas is investigated including terms beyond the random-phase approximation. We evaluate the charge response, the longitudinal and transverse spin response, and the mixed spin-charge response self-consistently in terms of the susceptibility functions of a noninteracting system. Exchange-correlation effects between electrons of spin {sigma} and {sigma}{prime} are included following Kukkonen and Overhauser, by using spin-polarization-dependent generalized Hubbard local-field factors {ital G}{sub {sigma}}{sup {plus_minus}} and {ital G}{sub {bar {sigma}}}{sup {plus_minus}}. The general condition for charge-density and spin-density-wave excitations of the system is discussed. {copyright} {ital 1996 The American Physical Society.}
