Episodic Transient Gamma-Ray Emission from the Microquasar Cygnus X-1
S. Sabatini, M. Tavani, E. Striani +58
Cygnus X-1 is the archetypal black hole (BH) binary system in our Galaxy. We report the main results of an extensive search for transient gamma-ray emission from Cygnus X-1 carried…
Optimal electron propagation on a quantum chain by a topological phase
S. Paganelli, G. L. Giorgi, F. de Pasquale
We study the quantum diffusion of an electron in a quantum chain starting from an initial state localized around a given site. As the wavepacket diffuses, the probability of recons…
Quantum phase diffusion of a Bose system: beyond the Hartree-Fock-Bogoliubov approximation
Ferdinando de Pasquale, Gian Luca Giorgi
A diffusion process is usually assumed for the phase of the order parameter of a Bose system of finite size. The theoretical basis is limited to the so called Bogoliubov approximat…
Two-spin entanglement induced by electron scattering in nanostructures
Gian Luca Giorgi, Ferdinando de Pasquale
We present a model where two magnetic impurities in a discrete tight-binding ring become entangled because of scattering processes associated to the injection of a conduction elect…
Mesoscopic continuous and discrete channels for quantum information transfer
F. de Pasquale, G. Giorgi, S. Paganelli
We study the possibility of realizing perfect quantum state transfer in mesoscopic devices. We discuss the case of the Fano-Anderson model extended to two impurities. For a channel…
Diffusive teleportation on a quantum dot chain
F. de Pasquale, G. Giorgi, S. Paganelli
We introduce a model of quantum teleportation on a channel built on a quantum dot chain. Quantum dots are coupled through hopping and each dot can accept zero, one or two electrons…
