Non-perturbative switching rates in bistable open quantum systems: from driven Kerr oscillators to dissipative cat qubits
Léon Carde, Ronan Gautier, Nicolas Didier +3
In this work, we use path integral techniques to predict the switching rate in a single-mode bistable open quantum system. While analytical expressions are well-known to be accessi…
Measures of quantum synchronization in continuous variable systems
A. Mari, A. Farace, N. Didier +2
We introduce and characterize two different measures which quantify the level of synchronization of interacting continuous variable quantum systems. The two measures allow to exten…
Photon production from the vacuum close to the super-radiant transition: When Casimir meets Kibble-Zurek
Giovanni Vacanti, Stefano Pugnetti, Nicolas Didier +4
The dynamical Casimir effect (DCE) predicts the generation of photons from the vacuum due to the parametric amplification of the quantum fluctuation of an electromagnetic field\cit…
Quantum dynamics in a camel-back potential of a dc SQUID
E. Hoskinson, F. Lecocq, N. Didier +7
We investigate the quantum dynamics of a quadratic-quartic anharmonic oscillator formed by a potential well between two potential barriers. We realize this novel potential shape wi…
