Kadanoff-Baym方程的完全碰撞近似:第一性原理实现

Complete collisions approximation to the Kadanoff-Baym equation: a first--principles implementation

D. Sangalli, A. Marini

摘要:

我们展示了亚皮秒时间尺度上的体硅载流子动力学。结果是从第一原理实现的Kadanoff-Baym方程内的广义Baym-Kadanoff近似和完整的碰撞近似。所得的散射项类似于半经典玻尔兹曼方程中描述的散射。

英文摘要:

We show carriers dynamics on bulk Silicon in the sub pico-second time scale. The results are obtained from a first-principles implementation of the the Kadanoff-Baym equations within the generalized Baym-Kadanoff ansatz and the complete collision approximation. The resulting scattering term is similar to the scattering described within the semi-classical Boltzmann equation.
