Dynamical exchange-correlation potentials in the spin channel for the two-dimensional electron liquid

The exchange-correlation kernel in the spin channel in an electron liquid has the structure f(xc,-)(L,T)(q,omega)->(q -> 0)A(omega)/q(2)+B-L,B-T(omega) in the limit of the long wavelength. Here L denotes the longitudinal component and T the transverse component relative to the direction of the wave vector q. A collection of exact results for A(omega) and B-L,B-T(omega) is obtained at limiting low and high frequency, respectively, in two dimensions. Based on these results, we further give approximate interpolations for A(omega) and B-L,B-T(omega) at all frequencies in the paramagnetic case.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000231564500051&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, Condensed MatterSCI(E)2ARTICLE7null7
