Conditional non-Hermitian acceleration of multiphoton atomic transitions
Marcos V. S. de Paula, Alexandre P. Costa, A. V. Dodonov
Continuous monitoring can convert a dissipative channel into a resource for accelerating otherwise slow multiphoton transitions. We consider a three-level atom in a configurati…
One- and multiphoton resonances in the light-atom interaction
Alexandre P. Costa, Alexandre V. Dodonov
The interaction between atomic systems and electromagnetic fields is central to modern physics and emerging quantum technologies. The Rabi models, in their semiclassical and quantu…
Metrological power of single-qubit dynamical Casimir effect in circuit QED
A. P. Costa, H. R. Schelb, A. V. Dodonov
We consider a nonstationary circuit QED system described by the quantum Rabi model, in which an artificial two-level atom with a tunable transition frequency is coupled to a single…
Quantum Rabi oscillations in the semiclassical limit: backreaction on the cavity field and entanglement
Alexandre P. Costa, Alexandre Dodonov
The goal of this chapter is to compare the predictions of the semiclassical Rabi model (SRM), which describes the interaction between a two-level system (qubit) and a classical mon…
