Observation of collapse and revival in a superconducting atomic frequency comb
E. S. Redchenko, M. Zens, M. Zemlicka +6
Recent advancements in superconducting circuits have enabled the experimental study of collective behavior of precisely controlled intermediate-scale ensembles of qubits. In this w…
Triggered Superradiance and Inversion Storage in a Hybrid Quantum System
Wenzel Kersten, Nikolaus de Zordo, Oliver Diekmann +6
We study the superradiant emission of an inverted spin ensemble strongly coupled to a superconducting cavity. After fast inversion, we detune the spins from the cavity and store th…
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…
Echo trains in pulsed electron spin resonance of a strongly coupled spin ensemble
Stefan Weichselbaumer, Matthias Zens, Christoph W. Zollitsch +4
We report on a novel dynamical phenomenon in electron spin resonance experiments of phosphorus donors. When strongly coupling the paramagnetic ensemble to a superconducting lumped…
Variational Renormalization Group for Dissipative Spin-Cavity Systems: Periodic Pulses of Nonclassical Photons from Mesoscopic Spin Ensembles
Himadri Shekhar Dhar, Matthias Zens, Dmitry O. Krimer +1
Mesoscopic spin ensembles coupled to a cavity offer the exciting prospect of observing complex nonclassical phenomena that pool the microscopic features from a few spins with those…
Dynamical Exploration of Amplitude Bistability in Engineered Quantum Systems
Andreas Angerer, Stefan Putz, Dmitry O. Krimer +9
Nonlinear systems, whose outputs are not directly proportional to their inputs, are well known to exhibit many interesting and important phenomena which have profoundly changed our…
Sustained photon pulse revivals from inhomogeneously broadened spin ensembles
Dmitry O. Krimer, Matthias Zens, Stefan Putz +1
A very promising recent trend in applied quantum physics is to combine the advantageous features of different quantum systems into what is called "hybrid quantum technology". One o…
