Decoherence as a Signature of an Excited State Quantum Phase Transition in Two Level Boson Systems
(American Institute of Physics, 2009)
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presence of quantum phase ...

Measurement of La-139(n,gamma) cross section at n_TOF
(American Institute of Physics, 2006)
The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance ...

Forced synchronization of a quantum dissipative dynamics
(American Institute of Physics, 2007)
We generalize the phenomenon of forced stochastic synchronization into the quantum domain within the framework of a paradigmatic spin-boson model (tunneling charge, or flipping spin 1/2 coupled to an environment) which ...

First experiment: Fragmentation of ions relevant for space and therapy
(IOP Publishing Ltd., 2013)
Nuclear fragmentation processes are relevant in different fields of basic research and applied physics and are of particular interest for tumor therapy and for space radiation protection applications. The FIRST (Fragmentation ...

A beyond mean-field study of the Tavis- Cummings model
(American Institute of Physics, 2019-09)
A beyond mean-field study of the Tavis-Cummings (TC) model is developed. This is the simplest model for describing the interaction of a radiation field with a system composed by an array of two-level atoms. The first ...

Inclusive breakup measurements of the 7Li+ 119Sn reaction
(Institute of Physics Publishing, 2020)
We present preliminary data of elastic scattering and inclusive breakup cross sections for the 7Li+ 119Sn reaction, recently measured at the Laboratori Nazionali del Sud (LNS-INFN) (Catania, Italy) at energies around the ...
