Local Measures of Entanglement and Critical Exponents at Quantum Phase Transitions
L. Campos Venuti, C. Degli Esposti Boschi, G. Morandi +2
We discuss on general grounds some local indicators of entanglement, that have been proposed recently for the study and classification of quantum phase transitions. In particular,…
Correlation between the parameters of the rate equation for simple aftershock sequences: implications for the forecasting of rates and probabilities
Paolo Gasperini, Barbara Lolli
We analyzed the correlations among the parameters of the Reasenberg and Jones (1989) formula describing the aftershock rate after a mainshock as a function of time and magnitude, o…
A dyadic decomposition approach to a finitely degenerate hyperbolic problem
Massimo Cicognani, Daniele Del Santo, Michael Reissig
We use the Littlewood-Paley decomposition technique to obtain a -well-posedness result for a weakly hyperbolic equation with a finite order of degeneration
On the gravitational field. A suggestion about a possible experiment
Bruno Ferretti
After a preliminary discussion of the relevance of the field nature of gravitation interaction, both for the fundamental interaction of particles and the topology of space time, a…
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…
The Ghirlanda-Guerra Identities
Pierluigi Contucci, Cristian Giardina'
If the variance of a Gaussian spin-glass Hamiltonian grows like the volume the model fulfills the Ghirlanda-Guerra identities in terms of the normalized Hamiltonian covariance.
