Figure 1
Two-orbital spin-exchange interaction in AEL atoms. (a) One atom in the ground state and one atom in the long-lived electronic state periodically “exchange” their nuclear spins because of the different interaction energy in the spin-singlet and spin-triplet two-particle states (note that in the graphical notation, the two-particle exchange symmetry is implicit [7]). (b) Dependence of the two-particle energy on the magnetic field . The spin dynamics is initiated by exciting the two atoms to the state at finite and then quenching the magnetic field to zero in order to create a superposition of the and states (dashed arrows).

(a) The points show the measured spin-exchange frequency as a function of the lattice depth . The data have been corrected for the small bias magnetic field in order to show the zero-field spin-exchange frequency. Each point is the average of at least three different measurements and the error bar shows the statistical error. The line is a fit based on the model described in the main text. (b) The points show the interaction energy of the state, calculated as the sum of the experimentally measured and the calculated by using . The shaded area shows the energy difference between ground and first excited lattice band.
