Decoherence of number states in phase-sensitive reservoirs
A. Serafini, S. De Siena, F. Illuminati
The non-unitary evolution of initial number states in general Gaussian environments is solved analytically. Decoherence in the channels is quantified by determining explicitly the…
High-Temperature Atomic Superfluidity in Lattice Boson-Fermion Mixtures
F. Illuminati, A. Albus
We consider atomic Bose-Fermi mixtures in optical lattices and study the superfluidity of fermionic atoms due to s-wave pairing induced by boson-fermion interactions. We prove that…
Dynamics of entanglement between two atomic samples with spontaneous scattering
Antonio Di Lisi, Silvio De Siena, Fabrizio Illuminati
We investigate the effects of spontaneous scattering on the evolution of entanglement of two atomic samples, probed by phase shift measurements on optical beams interacting with bo…
Determination of continuous variable entanglement by purity measurements
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We classify the entanglement of two--mode Gaussian states according to their degree of total and partial mixedness. We derive exact bounds that determine maximally and minimally en…
Entanglement and purity of two-mode Gaussian states in noisy channels
Alessio Serafini, Fabrizio Illuminati, Matteo G. A. Paris +1
We study the evolution of purity, entanglement and total correlations of general two--mode Gaussian states of continuous variable systems in arbitrary uncorrelated Gaussian environ…
Structure of multiphoton quantum optics. I. Canonical formalism and homodyne squeezed states
Fabio Dell'Anno, Silvio De Siena, Fabrizio Illuminati
We introduce a formalism of nonlinear canonical transformations for general systems of multiphoton quantum optics. For single-mode systems the transformations depend on a tunable f…
