摘要：

The dynamic exchange decoupling method for including exchange in the dielectric function of the homogeneous electron gas has been extended to one-dimensional systems, in both the free-electron and the tight-binding limit. In the free-electron model, the slope of the plasmon branch is almost unaffected by exchange effects. In the tight-binding model, the exchange interaction appreciably lowers this slope, except if the band is almost filled. © 1979 The American Physical Society.
