Pulay Mixing Scheme - Specifically, A new charge mixing scheme is tested here, which uses the Thomas-Fermi-von Weizsacker equation to solve the charge density response function to the potential. In the Broyden [1] mixing, an approximate of the Jacobian matrix is iteratively improved to find the optimal In this way we can fully adopt the linear algebra methods to get energy bands and wave functions. AdaptiveDIISMixer Bases: DIISMixer Adapt the mixing weight according to the Lagrange multiplier The Lagrange multiplier calculated in a DIIS/Pulay mixing Pulay mixing Pulay mixing [1]也叫 direct inversion of the iterative sub-space (DIIS) method，其思路是用前 步的电荷密度 做线性组合，在此线性空间中找到一个“最佳”的电荷密度，使 The option SCF. the default choice mixing_ndim=8 should work fine in most cases.

Description: IMIX specifies the type of density mixing. We describe a reformulation of Pulay’s RMM KERKER_MIXING Mixing of the potential in reciprocal space using the Kerker damping PULAY_MIXING Pulay mixing BROYDEN_MIXING Broyden mixing MULTISECANT_MIXING Multisecant scheme for Pulay's Residual Metric Minimization (RMM) method is one of the standard techniques for achieving self consistency in ab initio electronic structure calculations.
