PartialMeanFieldOperator

(will be published in fall 2018)

PartialMeanFieldOperator(op,rho,indices) returns a copy of op where any 2-particle terms acting on indices are replaced by Hartree-Fock mean-field theory, using the density rho (compare MeanFieldOperator()).

If the option AddDFTSelfInteraction is set to true the electron-self interaction is added on top to simulate the behaviour encountered in DFT.

Input

  • op : An operator.
  • rho : A density matrix.
  • indices : A list of indices.
  • Possible options are:
    • AddDFTSelfInteraction : bool defining if the electron self-interaction is to be included (Standard false).

Output

  • PMFop : A copy of op, where any 2-particle interaction acting on indices is replaced by mean-field theory.
