Correlation effects and the high-frequency spin susceptibility of an electron liquid: Exact limits
G. S. Atwal, N. W. Ashcroft
Spin correlations in an interacting electron liquid are studied in the high-frequency limit and in both two and three dimensions. The third-moment sum rule is evaluated and used to…

Singular Structure and Enhanced Friedel Oscillations in the Two-Dimensional Electron Gas
I. G. Khalil, N. W. Ashcroft, M. Teter
We calculate the leading order corrections (in ) to the static polarization , with dynamically screened interactions, for the two-dimensional electron gas. The co…

Relaxation of an Electron System : Conserving Approximation
G. S. Atwal, N. W. Ashcroft
The dynamic response of an interacting electron system is determined by an extension of the relaxation-time approximation forced to obey local conservation laws for number, momentu…
