Sub-shot-noise photon-number correlation in mesoscopic twin-beam of light
Maria Bondani, Alessia Allevi, Guido Zambra +2
We demonstrate sub-shot-noise photon-number correlations in a (temporal) multimode mesoscopic ( detected photons) twin-beam produced by ps-pulsed spontaneous non-degener…
Stability of quantum motion in regular systems: a uniform semiclassical approach
Wen-ge Wang, G. Casati, Baowen Li
We study the stability of quantum motion of classically regular systems in presence of small perturbations. Onthe base of a uniform semiclassical theory we derive the fidelity deca…
Reconstruction of photon statistics using low performance photon counters
G. Zambra, M. G. A. Paris
The output of a photodetector consists of a current pulse whose charge has the statistical distribution of the actual photon numbers convolved with a Bernoulli distribution. Photod…
Conservative chaotic map as a model of quantum many-body environment
Davide Rossini, Giuliano Benenti, Giulio Casati
We study the dynamics of the entanglement between two qubits coupled to a common chaotic environment, described by the quantum kicked rotator model. We show that the kicked rotator…
Semiclassical Theory of Amplification and Lasing
German J. de Valcarcel, Eugenio Roldan, F. Prati
In this article we present a systematic derivation of the Maxwell-Bloch equations describing amplification and laser action in a ring cavity. We derive the Maxwell-Bloch equations…
Regimes of stability of accelerator modes
Rebecca Hihinashvili, Tali Oliker, Yaniv S. Avizrats +3
The phase diagram of a simple area-preserving map, which was motivated by the quantum dynamics of cold atoms, is explored analytically and numerically. Periodic orbits of a given w…
