我们提出了一个有效的实现电子磁化率张量密度泛函理论。的磁化率表示通过其本征系统,这是使用迭代Lanczos对角化技术内的密度泛函微扰理论的磁化率张量计算。我们表明,在本征态的有限基础上的表示是足够准确的计算电子密度对外部电位的线性响应。一旦计算出本征系统表示,就可以以非常低的计算成本完成实际响应计算。该方法适用于水分子在偶极场作为基准系统。结果表明,在凝聚相的复杂无序系统的超分子相互作用的第一性原理计算的方法的潜力。
We present an efficient implementation of the electronic susceptibility tensor within density functional theory. The susceptibility is represented by means of its eigensystem, which is computed using an iterative Lanczos diagonalization technique for the susceptibility tensor within density functional perturbation theory. We show that a representation in a finite basis of eigenstates is sufficiently accurate to compute the linear response of the electronic density to external potentials. Once the eigensystem representation is computed, the actual response computation can be done at very low computational cost. The method is applied to the water molecule in a dipole field as a benchmark system. The results illustrate the potential of the approach for the first-principles calculation of supramolecular interactions in complex disordered systems in the condensed phase.
