MagneticField

MagneticField

is an option for Hamiltonian that specifies the applied external magnetic field.

Details and Options

  • The magnetic field determines the contribution to the Hamiltonian from the "MagneticDipole" interaction.
  • The field should be specified as a Cartesian vector.
  • For a toy-type system (no angular momentum) the magnetic field is disregarded.
  • Under the -coupling approximation, employed in the AtomicDensityMatrix package, magnetic coupling is allowed between two different -states only if they are components of the fine structure of one term. This can be specified by labeling the two states {term, lab1} and {term, lab2}, where term, lab1, and lab2 are arbitrary labels.
