Estimation for the discretely observed telegraph process
stefano m. iacus, nakahiro yoshida
The telegraph process , is supposed to be observed at equidistant time points . The unknown value of , the underlying rate of the Poi…
Two-body correlations and the superfluid fraction for nonuniform systems
Wayne M. Saslow, Davide E. Galli, Luciano Reatto
We extend the one-body phase function upper bound on the superfluid fraction in a periodic solid (a spatially ordered supersolid) to include two-body phase correlations. The one-bo…
Information/disturbance trade-off in single and sequential measurements on a qudit signal
Marco G. Genoni, Matteo G. A. Paris
We address the trade-off between information gain and state disturbance in measurement performed on qudit systems and devise a class of optimal measurement schemes that saturate th…
Another proof of Gell-Mann and Low's theorem
Luca Guido Molinari
The theorem by Gell-Mann and Low is a cornerstone in QFT and zero-temperature many-body theory. The standard proof is based on Dyson's time-ordered expansion of the propagator; a p…
Gamma Ray Bursts Flares detected and observed by the Swift Satellite
Guido Chincarini, Alberto Moretti, Patrizia Romano +11
The detection of flares with the Swift satellite triggered a lot of bservational and theoretical interest in these phenomena. As a consequence a large analysis effort started withi…
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…
