Multi-reference ab initio calculations of Hg spectral data and analysis of magic and zero-magic wavelengths.

We have identified magic wavelengths for S ↔ P (m = 0) transitions and zero-magic wavelengths for the P (m = 0) states of Hg atoms, analysed the robustness of the magic conditions with respect to wavelength and polarization imperfections. We show that the most experimentally feasible magic wavelength for the S ↔ P transition is 351.8 nm of π polarized light.
