Lanthanide systems often have multiple pairs of energy levels that are related to one another by a spin flip. These are called Kramers doublets. This function returns the effective g-tensor for the user-specified pair of levels.

Returns the effective g-tensor for a user-specified Kramers doublet, computed as described in http://dx.doi.org/10.1063/1.4793736; lanthanide systems often have multiple spin-flip-related energy-level pairs, and this function extracts the effective g-tensor for the selected pair.

Syntax

    g=geffect(spin_system,states)

Parameters

   states - the numbers of the states to use
            (numbered sequentially from the 
             lowest to the highest energy)

Returns

   g      - 3x3 g-tensor matrix in Bohr mag-
            neton units

Examples

See dy_lft_single.m file in examples/giant_spin folder of Spinach distribution.

Notes

Make sure that the pair of levels specified actually is a Kramers doublet.
