Two-Dimensional Chern Insulators: The Qi-Wu-Zhang ModelIn this chapter we construct two-dimensional insulators with nonvanishing Chern numbers, by promoting the time t in a an adiabatic pump cycle on a one-dimensional insulator, to a wavenumber k y . This construction not only gives us ...

LvActa Oceanologica Sinica, in pressBased on the simulation of a marine ecosystem dynamical model in the Bohai Sea, the Yellow Sea and the East China Sea, chlorophyll data are assimilated to study the spatially varying control parameters (CPs) by using the adjoint method. In this study, the...
本文主要介绍祁晓亮,吴咏时,张首晟06年提出的QWZ 模型[2],这是描述量子自旋霍尔效应(QSHE)中的Bernevig-Hughes-Zhang (BHZ)模型的基石,也被称之为"Half BHZ"模型。我会介绍这个模型的具体内容,如何在二维模型中做出边缘态。 QWZ模型 H^(kx,ky)=sinkxσ^x+sinkyσ^y+[u+coskx+cosky]σ^...
