Feedback-induced instabilities and dynamics in the Jaynes-Cummings model

Nikolett Német, Scott Parkins, Victor Canela +1

We investigate the coherence and steady-state properties of the Jaynes-Cummings model subjected to time-delayed coherent feedback in the regime of multiple excitations. The introdu…

Transfer matrix approach to determining the linear response of all-fiber networks of cavity-QED systems

Nikolett Német, Donald White, Shinya Kato +2

A semiclassical model is presented for characterizing the linear response of elementary quantum optical systems involving cavities, optical fibers, and atoms. Formulating the trans…

Dynamical behaviour of coupled atom-cavity systems in the single excitation limit

Ross Shillito, Nikolett Német, Scott Parkins

We investigate the time evolution of the photon-detection probability at various output ports of an all-fiber coupled cavity-quantum-electrodynamics (cavity-QED) system. The setup…

Comparison between continuous- and discrete-mode coherent feedback for the Jaynes-Cummings model

Nikolett Német, Alexander Carmele, Scott Parkins +1

Using the example of the Jaynes-Cummings model, we present a comparison between time-delayed coherent feedback mediated by reservoirs with continuous and discrete mode structures a…

Stabilizing quantum coherence against pure dephasing in the presence of quantum feedback at finite temperature

Nikolett Német, Scott Parkins, Andreas Knorr +1

A general formalism to describe the dynamics of quantum emitters in structured reservoirs is introduced. As an application, we investigate the optical coherence of an atom-like emi…
