论文摘要
我们引入了合同的平面波（CPWS），该波波（CPWS）满足了布里渊区圆环中的周期性量规，就像通常的Wannier功能一样。 CPW非常简单地作为平面波的总和。我们将能够使用CPW而不是Wannier函数来插值作为BZ中波向量的功能给出的物理量。此外，很容易通过CPWS补充高斯基地的集合。
We introduce the contracted plane waves (CPWs), which satisfy the periodic gauge in the Brillouin-zone torus as in the case of usual Wannier functions. CPWs are very simply given as the sum of plane waves. We will be able to use CPWs instead of the Wannier functions for the interpolation of physical quantities given as the function of wave vectors in BZ. Furthermore, it will be easy to complement the set of Gaussian bases by CPWs.
