# Solvable multistate model of Landau-Zener transitions in cavity QED

@article{Sinitsyn2016SolvableMM, title={Solvable multistate model of Landau-Zener transitions in cavity QED}, author={Nikolai A. Sinitsyn and Fuxiang Li}, journal={Physical Review A}, year={2016}, volume={93}, pages={063859} }

We consider the model of a single optical cavity mode interacting with two-level systems (spins) driven by a linearly time-dependent field. When this field passes through values at which spin energy level splittings become comparable to spin coupling to the optical mode, a cascade of Landau-Zener (LZ) transitions leads to co-flips of spins in exchange for photons of the cavity. We derive exact transition probabilities between different diabatic states induced by such a sweep of the field.
