11. We note that originally this equation was obtained by using the semiclassical approach. The presented quantum derivation due to closely follows the original semiclassical argumentation.

14. In practice, infinite temperature means kB T J.
15. We note, in passing, that one gets the same relaxation term for an atom in an optical lattice in the presence of spontaneous emission [A. R. Kolovsky, A. V. Ponomarev, and H. J. Korsch, Phys. Rev. A PLRAAN 1050-2947 10.1103/PhysRevA.66.053405 66, 053405 (2002)]. In this case, γ=Γ (ΩR /δ) 2, where ΩR is the Rabi frequency, δ is the detuning of the laser frequency from selected atomic transition, and Γ is the natural width of the selected transition.
