印第安纳大学物理系，印第安纳州布卢明顿 47405~1997 年 6 月 24 日接收！我们推导并评估了简单金属中光子阻力效应的流体动力学理论。考虑到单色光倾斜照射的 ajellium 表面，我们计算了稳定表面平行电流和沿表面法线感应的电动势。这些效应的大小可以通过多种方法来估计，从动量平衡论证，通过求和规则，到使用电子动力学的流体动力学描述进行详细的微观计算。有时不同的结果之间的比较有助于澄清现象的物理起源，特别是影响对表面敏感的程度。我们还概述了一种计算方法，该方法应该允许量子力学动力学的易于处理的结合。@S0163-1829~97！04247-1#I。介绍
Department of Physics, Indiana University, Bloomington, Indiana 47405~Received 24 June 1997!We derive and evaluate a hydrodynamic theory of photon-drag effects in simple metals. Considering ajellium surface obliquely illuminated by monochromatic light, we calculate both the steady surface-parallelcurrent and the emf induced along the surface normal. The sizes of these effects are estimated with a varietyof approaches, ranging from momentum-balance arguments, through sum rules, to detailed microscopic cal-culations using a hydrodynamic description of the electrons’ dynamics. Comparisons between the sometimesdifferent results help clarify the physical origin of the phenomena, in particular, the extent to which effects aresurface sensitive. We also outline a calculational approach that should allow a tractable incorporation ofquantum-mechanical dynamics.@S0163-1829~97!04247-1#I. INTRODUCTION
