摘要翻译：
其基本的经典动力学是混沌的系统在其量子力学中表现出混沌的特征。我们探讨了用含时密度泛函理论(TDDFT)研究单独由电子相互作用引起混沌的可能性。最近邻水平间距统计量原则上可以从TDDFT中准确和直接地获得。我们讨论了TDDFT线性响应过程如何揭示单独由电子相互作用引起的混沌机制。一个简单的双电子量子点模型强调了在TDDFT中超越绝热近似的必要性。

英文摘要：
Systems whose underlying classical dynamics are chaotic exhibit signatures of the chaos in their quantum mechanics. We investigate the possibility of using time-dependent density functional theory (TDDFT) to study the case when chaos is induced by electron-interaction alone. Nearest-neighbour level-spacing statistics are in principle exactly and directly accessible from TDDFT. We discuss how the TDDFT linear response procedure can reveal the mechanism of chaos induced by electron-interaction alone. A simple model of a two-electron quantum dot highlights the necessity to go beyond the adiabatic approximation in TDDFT.
