Environment-governed dynamics in driven quantum systems
S. Gasparinetti, P. Solinas, S. Pugnetti +2
We show that the dynamics of a driven quantum system weakly coupled to the environment can exhibit two distinct regimes. While the relaxation basis is usually determined by the sys…
Geometric phases in superconducting qubits beyond the two-level-approximation
S. Berger, M. Pechal, S. Pugnetti +5
Geometric phases, which accompany the evolution of a quantum system and depend only on its trajectory in state space, are commonly studied in two-level systems. Here, however, we s…
Quantum transducer in circuit optomechanics
Nicolas Didier, Stefano Pugnetti, Yaroslav M. Blanter +1
Mechanical resonators are macroscopic quantum objects with great potential. They couple to many different quantum systems such as spins, optical photons, cold atoms, and Bose Einst…
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…
Floquet theory of Cooper pair pumping
Angelo Russomanno, Stefano Pugnetti, Valentina Brosco +1
In this work we derive a general formula for the charge pumped in a superconducting nanocircuit. Our expression generalizes previous results in several ways, it is applicable both…
Detecting phonon blockade with photons
Nicolas Didier, Stefano Pugnetti, Yaroslav M. Blanter +1
Measuring the quantum dynamics of a mechanical system, when few phonons are involved, remains a challenge. We show that a superconducting microwave resonator linearly coupled to th…
