# arc.calculations_atom_single.StarkMap.getPolarizability#

StarkMap.getPolarizability(maxField=10000000000.0, showPlot=False, debugOutput=False, minStateContribution=0.0)[source]#

Returns the polarizability of the state (set during the initalization process).

Fits offset of the energy level of the state to $$\frac{1}{2} \alpha_0 E^2$$, where $$E$$ is the applied static electric field, and returns fitted value $$\alpha_0$$

Parameters
• maxField (float, optional) – maximum field (in V/m) to be used for fitting the polarizability. By default, max field is very large, so it will use eigenvalues calculated in the whole range.

• showPlot (bool, optional) – shows plot of calculated eigenValues of the given state (dots), and the fit (solid line) for extracting polarizability

• debugOutput (bool, optional) – if True prints additional information usefull for debuging. Set to false by default.

Returns

scalar polarizability in units of MHz cm $$^2$$ / V $$^2$$

Return type

float
