SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
Limit theorems for a class of identically distributed random variables
Patrizia Berti, Luca Pratelli, Pietro Rigo
A new type of stochastic dependence for a sequence of random variables is introduced and studied. Precisely, (X_n)_{n\geq 1} is said to be conditionally identically distributed (c.…
Long time behavior of non-autonomous Fokker-Planck equations and the cooling of granular gases
Bertrand Lods, Giuseppe Toscani
We analyze the asymptotic behavior of linear Fokker-Planck equations with time-dependent coefficients. Relaxation towards a Maxwellian distribution with time-dependent temperature…
Single-spin asymmetries with two-hadron fragmentation functions
Alessandro Bacchetta, Marco Radici
Using the formalism of two-hadron fragmentation functions, we discuss single-spin asymmetries occurring in the production of two hadrons in the current region of deep inelastic sca…
Economical Phase-Covariant Cloning of Qudits
Francesco Buscemi, Giacomo Mauro D'Ariano, Chiara Macchiavello
We derive the optimal N to M phase-covariant quantum cloning for equatorial states in dimension d with M=kd+N, k integer. The cloning maps are optimal for both global and single-qu…
Unexpected effect of Ru-substitution in lightly doped manganites
Lorenzo Malavasi, M. Cristina Mozzati, Cristina Tealdi +3
In this Communication we report about the unexpected effect of ruthenium doping in sodium ligthly-doped manganites. This effect seems to be in contrast with the usual model applied…
