本文用动力学无规相近似研究了层状电子气中的多体效应。计算了电子自能、有效质量和寿命随电子密度和层间间距的变化。结果表明，在二维和三维的相互作用的电子气的行为有质的不同。
Many-body effects in a layered electron gas are studied using the dynamical random-phase approximation. The electron self-energy, effective mass, and lifetime are calculated as functions of electron density and interlayer separation. The results show behavior qualitatively different from that of the interacting electron gas in two and three dimensions.
