ElectricField

ElectricField

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

Details and Options

  • The electric field determines the contribution to the Hamiltonian from the "ElectricDipole" interaction and the "Polarizability" interaction.
  • The field should be specified as a Cartesian vector. For toy-type atomic systems (no angular momentum), a single component can be given instead. If a vector is given for a toy system, the electric field is converted to a scalar by taking the norm, if there is more than one nonzero Cartesian component, or by taking the nonzero Cartesian component, if there is only one.
  • OpticalField can be used to write an oscillating field with specified frequency and polarization for use as a value for ElectricField.
