The effective mass that approximately describes the effect of a classical homogeneous gravitational field on an interacting atom-radiation field system is determined within the framework of the Jaynes-Cummings model. By taking into account both the atomic motion and gravitational field, a full quantum treatment of the internal and external dynamics of the atom is presented. By solving exactly t...

We present a theoretical scheme based on su(2) algebra to investigate the influence of homogeneous gravitational field on the quantum nondemolition measurement of atomic momentum in dispersive JaynesCummings model. In the dispersive Jaynes-Cummings model, when detuning is large and the atomic motion is in a propagating light wave, we consider a two-level atom with quantized cavity-field in the ...

The Jaynes-Cummings model describing the interaction of a single linearlypolarized mode of the quantized electromagnetic field with an isolated two-level atom is generalized to the case of atomic levels degenerate in the projections of the angular momenta on the quantization axis, which is a usual case in the experiments. This generalization, like the original model, obtains the explicit soluti...

Coupling $N$ identical emitters to the same field mode is well-established method enhance light matter interaction. However, resulting $\sqrt{N}$ boost of coupling strength comes at cost a "linearized" (effectively semi-classical) dynamics. Here, we instead demonstrate new approach for enhancing constant \textit{single} quantum emitter, while retaining nonlinear character light-matter We consid...

The authors theoretically study the polariton dynamics in single- and two-body Jaynes-Cummings systems identify mechanisms that allow interchange of branches. results provide insights into controlling Mott insulator to superfluid transition.
