Representation

Representation

is an option for DensityMatrix and related functions that specifies the representation basis for the density matrix.

Details and Options

  • Possible option values include "Zeeman", meaning expansion of operators over the Zeeman basis set , and "PolarizationMoments", meaning expansion over the basis of polarization moments .
  • The value Representation->Automatic specified for any function other than DensityMatrix means to use the default value specified in Options[DensityMatrix].
