Spin correlations in the low-density electron system
(1993-02/15)
The authors have calculated the spin susceptibility x(q,) within a microscopic model over the full range of densities of the electron liquid in the paramagnetic state. Electron-electron interactions are described by static ...
Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems
(1992-03/01)
Motivated by recent work on the critical resistivity of gadolinium, a detailed study has been made of the temperature dependence of the two-point vertex function in the large-momentum regime. The operator-project expansion ...
