Electron Transport from Quantum Kinetic Monte Carlo Simulations
摘要:
本文提出了一种精确的量子动力学蒙特卡罗方法来计算一维费米哈伯德模型的电子输运。该方法是直接制定的实时和可应用于提取一般的相互作用费米子模型的时间相关的动力学在1D。当与密度泛函理论和极大局域化Wannier函数相结合时,我们的方法可以用来预测存在界面的材料中的电子输运。我们的方法的第一个应用程序的案例研究$α$ -石英介质击穿似乎很有前途。
英文摘要:
An exact Quantum Kinetic Monte Carlo method is proposed to calculate electron transport for 1D Fermi Hubbard model. The method is directly formulated in real time and can be applied to extract time dependent dynamics of general interacting Fermion models in 1D. When coupled with Density Functional Theory and Maximally Localized Wannier Functions, our method can be used to predict electron transport in materials in presence of interfaces. The first application of our method on case study of $α$-quartz dielectric breakdown seems promising.
