论文摘要
假设量子干扰效应在存在较强的自旋轨道相互作用和强晶格电位的情况下,量子干扰效应破坏了时间反转的对称性,则研究了二维系统的整体电导率。这项研究是通过直接对角线化进行的,以探索非线性反应状态。该系统显示一个量化的电导率,取决于电场的强度,在特定条件下,零电场处的电导率极限显示出非变化值。
The bulk conductivity of a two-dimensional system is studied assuming that quantum interference effects break time-reversal symmetry in the presence of strong spin-orbit interaction and strong lattice potential. The study is carried out by direct diagonalization in order to explore the nonlinear-response regime. The system displays a quantized conductivity that depends on the intensity of the electric field and under specific conditions the conductivity limit at zero electric field shows a nonvanishing value.
