Ultrafast Excitation Exchange in a Maxwell-Fish-Eye Lens
Oliver Diekmann, Dmitry O. Krimer, Stefan Rotter
The strong coupling of quantum emitters to a cavity mode has been of paramount importance in the development of quantum optics. Recently, also the strong coupling to more than a si…
Driven-dissipative time crystalline phases in a two-mode bosonic system with Kerr nonlinearity
L. R. Bakker, M. S. Bahovadinov, D. V. Kurlov +3
For the driven-dissipative system of two coupled bosonic modes in a nonlinear cavity resonator, we demonstrate a sequence of phase transitions from a trivial steady state to two di…
Periodic cavity state revivals from atomic frequency combs
Matthias Zens, Dmitry O. Krimer, Himadri S. Dhar +1
Spin ensembles with a comb-shaped spectrum have shown exciting properties as efficient quantum memories. Here, we present a rigorous theoretical study of such atomic frequency comb…
Critical phenomena and nonlinear dynamics in a spin ensemble strongly coupled to a cavity. II. Semiclassical-to-quantum boundary
Matthias Zens, Dmitry O. Krimer, Stefan Rotter
We numerically study the dynamics and stationary states of a spin ensemble strongly coupled to a single-mode resonator subjected to loss and external driving. Employing a generaliz…
Critical phenomena and nonlinear dynamics in a spin ensemble strongly coupled to a cavity. I. Semiclassical approach
Dmitry O. Krimer, Matthias Zens, Stefan Rotter
We present a theoretical study on the nonlinear dynamics and stationary states of an inhomogeneously broadened spin ensemble coupled to a single-mode cavity driven by an external d…
Few-mode geometric description of a driven-dissipative phase transition in an open quantum system
Dmitry O. Krimer, Mikhail Pletyukhov
By example of the nonlinear Kerr-mode driven by a laser, we show that hysteresis phenomena in systems featuring a driven-dissipative phase transition (DPT) can be accurately descri…
