摘要：
研究了强耦合二维电子液体中极化效应对面内阻止本领贡献的高速射弹极限。基于矩量法的介电形式主义。损失函数的频率矩使用模型哈密顿量计算，包括与k的逆幂成比例的二维库仑相互作用势。我们证明了高速渐近线的主导项，像在随机相位近似，不受相关性。
英文摘要：
We study the high-velocity-projectile limit of the polarizational contribution to the in-plane stopping power in a strongly coupled two-dimensional electron liquid. The dielectric formalism based on the method of moments is employed. The frequency moments of the loss function are calculated using the model Hamiltonian including the two-dimensional Coulomb interaction potential proportional to the inverse power of k. We prove that the leading term of the high-velocity asymptote, like in the random-phase approximation, is not affected by correlations.
