Exotic fluorescence spectrum of a superconducting qubit driven simultaneously by longitudinal and transversal fields

Exotic fluorescence spectrum of a superconducting qubit driven simultaneously by longitudinal and transversal fields

We study the fluorescence spectrum from a two-level system with a controllable energy separation modulated by the longitudinal field and excited by the transversal field. Combining the rotating-wave approximation and the Floquet theory, we derive a formal solution to the Bloch equations in the prese...
