Abstract
The propagation of surface waves on a quantum plasma half-space is investigated, taking into account the electron exchange-correlation effect. Using the modified quantum hydrodynamic model in conjunction with the Poisson equation, the dispersion relation of surface waves is obtained. It is found that due to the presence of electron exchange-correlation effect the wave frequency is shifted to lower frequencies. For different ranges of Brueckner parameter rs, the effect of electron exchange-correlation is investigated. It is indicated that for weak coupling region with rs < 0.1, the wave frequency remains unchanged and in this region the effect of electron exchange-correlation is negligible. For moderate coupling region, i.e., (0.1 < rs < 1), the influence of electron exchange-correlation is important and as rs increases, the electron exchange-correlation effect also increases.
