The striking nonlinear effects exhibited by cavity QED systems make them a powerful tool in modern condensed matter and atomic physics [1– 4]. A recently discovered example is the quantized pumping of energy into a cavity by a strongly-coupled, periodically-driven spin [5, 6]. We uncover a remarkable feature of these energy pumps: they coherently translate, or boost, a quantum state of the cavity in the Fock basis. The required ultra-strong coupling may be achieved in a rotating frame. Boosting… Expand

Photon pumping in a weakly-driven quantum cavity–spin system
Abstract We investigate the photon pumping effect in a topological model consisting of a periodically driven spin-1/2 coupled to a quantum cavity mode out of the adiabatic limit. In the strong-driveExpand
